Closes#2248.
Completes SEP-2640 support across all three clients, and closes the one
obligation #2234 deliberately left open.
- `checkSkillFrontmatterMatch` compares a served SKILL.md's own YAML
frontmatter against the entry the listing advertised, field by field. No
digest can cover this: a digest is taken over the bytes the server served,
so it proves the file was not altered in transit and says nothing about
whether the listing described it honestly. Needs a real YAML parser; `yaml`
was already a root dependency, so this adds no package — but it does newly
put it on core/'s import graph, hence the three bundler `external` lists.
- `resources/directory/read`: result schemas defined against the normative
text, `InspectorClient.readResourceDirectory`, a Directory section on the
Skills screen, and `--method resources/directory/read` in the CLI. The
client refuses the call locally when the server did not declare
`directoryRead`, which is the SEP's MUST NOT. A child the directory lists
but the entry does not is marked `not listed` rather than merged into the
manifest — the SEP calls a directory result a live observation and forbids
treating it as extending the manifest.
- CLI: `skills/list`, `skills/get` and `resources/directory/read`, plus
`--verify` — one NDJSON report per skill, a summary on stderr, exit 7 on a
violation. Reads are sequential; a conforming manifest may declare 512
entries.
- TUI: a Skills pane, shown only when the server declares the extension. Each
row carries its conformance verdict as a glyph as well as a colour, since
the pane is read over ssh and through script(1). Enter verifies.
- `verifySkills` re-throws `AuthRecoveryRequiredError` rather than recording
it per file: it says the session's authorization expired, so absorbing it
would report N identical read failures and swallow the error the TUI and
the web commands key off to reauthorize.
Two open questions settled, both in code comments where they will be found:
`skills/get` carries no caching attributes because SEP-2640 leaves the
question open in as many words, so requiring them would fail a conforming
server; and there is no `PagedSkillsState` because every consumer of this
list is a whole-catalog verdict — computed over page one of three, "this
server's skills conform" is not merely partial but wrong.
The fixture grows two skills, both for checks that were otherwise
undemonstrable: `lying-listing` (listing and file disagree, digest still
verifies) and `stale-manifest` (serves a file its manifest does not declare).
