+docs(spec): state that a `permissions` key on a skill is REJECTED, not stripped (#7567)
+
+`SkillSchema`'s docblock carried a `NOTE` paragraph saying an authored
+`permissions` key "is unknown to this schema and silently stripped at parse
+time." That was true once, but the behaviour changed: `SkillSchema` is a
+`strictObject` whose `guidance.permissions` entry now REFUSES an authored
+`permissions` key outright, with a located message telling the author to gate
+at the agent level instead (`agent.access` / `agent.permissions`, enforced
+since #1884). The docblock's stale present tense was the only thing still
+saying "stripped" — a reader could conclude the authoring surface was still
+lax exactly where it is now strict.
+
+Only the `NOTE` paragraph's wording changes: it now says the key is rejected
+at parse time and points at the located refusal message
+(`guidance.permissions`) below it in the same file. The refusal message
+itself is untouched — its own "this was stripped in silence" phrase narrates
+the historical reason for the refusal, not current behaviour, and stays
+correct as written. Every input parses byte-identically before and after this
+change (`git diff` touches only comment lines); `pnpm --filter @objectstack/spec
+typecheck` and the full spec test suite (9840 tests) are green, and
+`check:docs` reports all 231 generated files still in sync — this paragraph
+is an inner/property-level TSDoc comment, not the module-level blurb
+`build-docs.ts` renders, so no generated doc changes.
+
+Adds a patch changeset for `@objectstack/spec`, following the #7444 / #7473 /
+#7565 precedent for describe/TSDoc-only spec docs fixes.
