chore: version dead-prop removal as minor per launch-window policy (#2377)

The whole publishable set is in the Changesets fixed group, so a `major`
would promote the entire monorepo. Breaking spec cleanups ride the minor
line during the launch window (precedent: #2402 → 11.1.0).

 feat(spec)!: remove dead author-facing metadata properties (#2377, ADR-0049 enforce-or-remove)
 
+Breaking spec-surface removal, versioned as `minor` per the launch-window changeset
+policy (a `major` would promote the whole fixed-group monorepo; breaking cleanups ride
+the minor line, as with #2402 → 11.1.0).

 Removes a batch of spec properties that parsed but had **no runtime consumer** —
 authoring them was a false affordance (especially dangerous for AI-authored
 metadata). Verified dead against the liveness ledger (`packages/spec/liveness/*.json`)
