* feat(#1430): versioned capability manifest + native stamping (ADR-1244 Phase 1)
Make the capability manifest versioned — the data substrate the Capability
Ecosystem (ADR-1244) keys off:
- capability.json gains a REQUIRED semver `version` plus the optional
ecosystem envelope (`engines.gsd`, `compatVersions`, `integrity`,
`provenance`); the build-time conformance validator enforces them via a new
`validateVersionEnvelope()` (exported for the Phase 2 runtime overlay).
- All 32 native capabilities stamped with `version` (= package version,
lockstep) + `engines.gsd`; `sync-manifest-versions.cjs` gains a glob sweep
that keeps them in sync, and the issue-844 regression guard is extended.
- Strict SemVer 2.0.0 grammar blocks metacharacter/space/unicode smuggling in
version strings; range/integrity fields are shape-validated (satisfaction
and the load-time gate are deferred to Phase 2/4).
- Capability rel-paths emitted forward-slash for cross-platform git correctness.
