feat(extension): present restricted commands as absent and trim skills

Add host-level opt-in concealment for plugin-restricted commands while keeping Restrict enforcement and the established legacy and YAML behavior unchanged.

Compose external wrapper-owned embedded skill trees with fail-closed Base, Allow, Remove, Overlay, and structured reference remaps. Retire CLI-owned dead affordances across help, completion, flags, notices, diagnostics, and recovery.

Keep presentation and skill state build-local and single-sourced, preserve typed producer errors, and cover source compatibility, multi-build isolation, failure paths, and real external fork integrations.

 We recommend using the Lark/Feishu bot integrated with this tool as a private conversational assistant. Do not add it to group chats or allow other users to interact with it, to avoid abuse of permissions or data leakage.
 
+To reduce the security risks associated with access token theft, the CLI sends a minimal set of risk-control signals with OpenAPI requests made to exact official Feishu/Lark HTTPS domains. These signals are used to help identify anomalous API activity. This protection is enabled by default. The information sent is limited to:

-AGENT QUICKSTART (driving this as an agent? start here):
-    Browse commands:  lark-cli <domain> --help            # +shortcuts (preferred) and raw API resources
-    Inspect a call:   lark-cli schema <service>.<resource>.<method>   # params, types, scopes, examples
-    Prefer a +shortcut over the raw API resource when one matches the task.
-    Risk: each command's --help shows read | write | high-risk-write;
-          high-risk-write needs --yes, only after the user confirms.
-    On any API call: --jq <expr> filters JSON output, --dry-run previews the request (runs nothing).

 You should see `audit` in the plugin list.
 
+That is sufficient for a hook-only plugin such as the audit observer. A
+wrapper main does not compile lark-cli's repository-root `content_embed.go`,
+so distribution content is a separate, explicit host choice.
+
+### Ship skills and command guidance
+
+If the distribution exposes embedded skills or customizes them with
+`EmbeddedSkills`, copy or generate both content trees under the wrapper
+package and wire both:
+
+```go
+package main
+
+import (
+    "embed"
+    "io/fs"
+    "os"
+
+    _ "github.com/me/myplugin"

+    }
+    cmd.SetEmbeddedSkillContent(skillTree)
+    cmd.SetEmbeddedAffordanceContent(affordanceTree)
+    os.Exit(cmd.Execute())
+}
+```
+
+`go:embed` only reads files in the package being compiled; it cannot reach
+into the replaced `github.com/larksuite/cli` module. Each
+`skills/<name>/` must contain `SKILL.md`. The `affordance/*.md` files are the
+structured source for command help and canonical skill references; ship the
+ones for the domains your distribution retains. Without
+`SetEmbeddedSkillContent`, `skills list` has no base content and an `Allow` or
+`Remove` overlay deliberately aborts startup. A plugin may instead provide a

   widen another's policy). YAML policy at `~/.lark-cli/policy.yml` (which
   may itself list several rules under `rules:`) is shadowed by any plugin
   Restrict.
+- A plugin may call `EmbeddedSkills()` at most once to customize the embedded
+  skill tree — `Allow` keeps only the listed skills (the allow-list
+  counterpart of `Rule.Allow`, so a CLI upgrade cannot widen the build;
+  `Remove` wins over `Allow`, and `Overlay` entries are exempt), `Remove`
+  drops skills, `Overlay` adds/replaces ones, or swap the whole `Base` —
+  layered over the host-provided base skill tree. The repository's root
+  lark-cli binary wires its default in `content_embed.go`; an external fork
+  main must call `cmd.SetEmbeddedSkillContent` as shown above (unless its
+  plugin supplies `Base`) and should wire `cmd.SetEmbeddedAffordanceContent`
+  for command guidance. `EmbeddedSkills()` implies `FailClosed`: it
+  declares distribution assets, and silently falling back could republish
+  content the distribution explicitly removed or replaced. Removing a skill
+  drops its `skills read` content and every framework-owned structured help
+  block that depends on it; it does NOT disable matching commands (use
+  `Restrict()` for that). The inverse is also explicit: concealing a command
+  does not automatically delete its skill content. Command policy and
+  distribution assets are independent axes; use `EmbeddedSkills` when both
+  must be trimmed.
+  `ReferenceRemaps` can rename a whole referenced skill while preserving
+  relative paths, or override one exact reference:
+
+  ```go
+  EmbeddedSkills(&platform.SkillsOverlay{
+      Base: customizedSkills,
+      ReferenceRemaps: []platform.SkillRefRemap{
+          platform.RemapSkillRef("lark-doc", "acme-docx"),
+          platform.RemapSkillRef(
+              "lark-doc/references/lark-doc-fetch.md",
+              "acme-docx/guides/fetch.md",
+          ),
+      },
+  })
+  ```
+
+  Remaps apply only to structured CLI help/affordance references; they never
+  scan or rewrite arbitrary prose or links inside Skill Markdown. An explicit
+  remap to a missing target aborts startup, while an unmapped canonical
+  reference removed from the final tree causes its complete dependent help
+  block to be omitted. Only ONE plugin per binary may
+  contribute a `SkillsOverlay`; two DISTINCT plugins is a deliberate
+  `multiple_skills_overlay_plugins` error. The top-level skill set and
+  each skill's owning FS are snapshotted during CLI build; files inside an
+  owned skill directory remain live. Both `Base` and `Overlay` must
+  contain only valid skill directories with `SKILL.md`.
+- A command denied by a Rule is hidden from normal command discovery and
+  returns `validation/failed_precondition` with its policy source, rule, and
+  reason code in the recovery hint. This is the established `Restrict`
+  contract for both plugin and yaml sources. A distribution that wants
+  plugin-restricted commands to look absent must opt in from its wrapper main
+  with `cmd.ExecuteWithOptions(cmd.ConcealRestrictedCommands(...))`;
+  presentation is a host choice, not part of `Rule` or `Capabilities`. One
+  carve-out: a command already retired by the user's strict-mode setting
+  keeps its strict-mode identity error even when a plugin Rule also
+  matches it — strict-mode is a user-side security boundary and is never
+  re-labelled.
+  A wrapper may customize the absent-capability message:
+
+  ```go
+  os.Exit(cmd.ExecuteWithOptions(
+      cmd.ConcealRestrictedCommands(
+          cmd.UnavailableMessage("capability not shipped by this distribution"),
+      ),
+  ))
+  ```
+- `config policy show` / `config plugins show` stay executable under any
+  plugin policy (hidden from help when their domain is denied) so an
+  operator can still inspect the rule that locked the build. A concealed
+  distribution can remove those escape hatches with the host-side
+  `cmd.HidePolicyDiagnostics()` presentation option.
