feat(spec)!: remove deprecated aiStudio/aiSeat capability aliases (#3308) (#3329)

The one-cycle deprecation window from #3265 is over and a major release is being prepared, so the legacy camelCase `requires` aliases are dropped. `aiStudio`/`aiSeat` are no longer canonicalized to `ai-studio`/`ai-seat` — they now reject as unknown tokens in defineStack (the #3302 end-state).

- spec: remove DEPRECATED_PLATFORM_CAPABILITY_ALIASES + canonicalizePlatformCapability; isKnownPlatformCapability no longer canonicalizes; defineStack drops canonicalizeStackRequires.
- cli: serve resolver no longer canonicalizes raw-artifact requires.
- Regenerate api-surface.json (4 export deletions); sync ADR-0087 spec-changes.json + protocol-upgrade-guide.md (pre-existing v16 drift surfaced by the path-filtered check).

Breaking change shipped as minor per the launch-window convention. Cloud objectos-runtime (pinned to an older framework) follows on its next .framework-sha bump.

+feat(spec)!: remove deprecated `aiStudio`/`aiSeat` capability aliases (#3308)
+
+**BREAKING** (shipped as minor per the launch-window convention). The one-cycle
+deprecation window from #3265 is over: the legacy camelCase `requires` spellings
+`aiStudio`/`aiSeat` are no longer canonicalized to `ai-studio`/`ai-seat` — they
+are now plain unknown tokens, rejected by `defineStack` like any other typo.
+
+- Removed exports `DEPRECATED_PLATFORM_CAPABILITY_ALIASES` and
+  `canonicalizePlatformCapability` from `@objectstack/spec`; `isKnownPlatformCapability`
+  no longer canonicalizes.
+- `defineStack` no longer rewrites aliases (the `canonicalizeStackRequires` pass
+  is gone); the serve resolver no longer canonicalizes raw-artifact `requires`.
+
+Migration: use the canonical kebab-case tokens `ai-studio` / `ai-seat`. All
+first-party configs were migrated in #862/#863; only stacks still carrying the
+legacy spelling are affected. Cloud's `objectos-runtime` (pinned to an older
+framework) follows on its next `.framework-sha` bump.

+## Protocol 15 → 16

+Protocol 16 flipped `DashboardWidgetSchema` to `.strict()` (framework#3251, ADR-0021 endpoint): an undeclared top-level widget key is now a loud parse error instead of a silent strip (ADR-0049 enforce-or-remove, ADR-0078 no-silently-inert). The inline analytics shape it most often catches (`object`+`categoryField`+`valueField`+`aggregate`, pivot `rowField`/`columnField`) was already removed at protocol 9, so no mechanical rewrite applies; the residue is the strictness itself, delegated to the author because an arbitrary unknown key has no lossless canonical target.
