The skill detail drawer could only show and edit SKILL.md; the bundle
files under scripts/ and references/ had no console surface, and
templates/ was readable by agents but absent from the canonical
store's bucket set.
- admin endpoints on /api/v1/skills/{id}/files: list (self-heals an
empty canonical store from on-disk files), read, upsert, delete.
Writes update the canonical row, materialize the workspace cache,
and re-resolve the skill so agents pick changes up immediately.
Path envelope enforces the three buckets and blocks traversal;
builtin skill files stay read-only; virtual skills own no files.
- templates/ becomes a first-class DB-persisted bucket shared across
the syncer, the workspace write/delete envelope, and prune guards.
- the agent-facing write_file action now mirrors into the canonical
store and re-resolves instead of writing only the local filesystem.
- SkillMarket detail drawer gains a Files tab: grouped list, viewer,
inline editor, create and delete, refetched on every entry.
