* feat(#1435): capability matrix (generated + drift-guarded) + trust-model doc consolidation
ADR-1244 Phase 6. Adds the capability matrix reference, generated FROM the committed registry so it
can never drift from the actual capability set:
- scripts/gen-capability-matrix.cjs (--write / --check); --check is a CI drift guard.
- tests/capability-matrix-sync.test.cjs (4 tests): drift guard, buildMatrix==committed, every cap
present, no placeholders.
- docs/reference/capability-matrix.md regenerated from the registry (release-stable: shows engines.gsd,
omits the lockstep per-cap version that would churn the file every release).
- Consolidated the duplicate trust-model doc: deleted docs/explanation/the-capability-trust-model.md,
merged its content into capability-trust-model.md, redirected ~10 references; no stale links remain.
- Diataxis verification (now that gsd capability is a real command): corrected the matrix's third-party
section — the matrix is the first-party catalogue; the overlay-aware view of installed third-party
capabilities is 'gsd capability list', not this generated file.

* fix(#1435): address code-review — non-vacuous matrix test + generator polish
- capability-matrix-sync.test.cjs: assert the 'security registers a ship:pre gate' precondition
unconditionally so the extension-point check can never degrade to a vacuous pass on registry drift.
- gen-capability-matrix.cjs: warn (stderr) on an unknown loop point at generation time; rename
enginesOf -> fmtEngines for consistency with the other fmt* helpers (output unchanged).
- capability-trust-model.md: point the two how-to links at the real files
(import-a-capability-from-a-url.md, version-a-capability.md) instead of the bare directory.
