skill-update	Update an existing skill in the jsc skill set. List all skills, let the user pick one, ask update details via decision tree, apply the change, re-check against the guidelines checklist until it passes, then open a PR via jsc-git pr. Use for modifying a skill; not for creating (skill-new) or removing (skill-delete).

skill-update — update a skill

Single source of guidelines: ../../references/guidelines.md.

Flow

1. List every skill in the skill set: scan jsc-*/skills/*/SKILL.md and present a "domain / name / description" list.
2. Let the user pick the skill to update.
3. Ask for update details via the jsc-ask:ask decision tree (change the goal? the trigger? the flow? move rules down to a hook or a tool?). Every option states its impact scope (example: renaming breaks the existing invocation command).
4. Update the skill — this step MUST run as a sub agent: modify SKILL.md and related files, sync the domain README's 「Skills 目錄」 section, and bump the version in all three manifests.
5. Check every item of the guidelines.md audit checklist. On any failure, return to step 3: ask again and fix, until all items pass.
6. Call jsc-git:pr to open a Push Request.
