v2 platform runtime (docs 22 Phase 2/4/7 + 17): Project/Environment + Config + Storage + Observability

- Project/Environment model with default environments (dev/staging/prod)
- Config Runtime: cascade resolution (platform→org→project→env), secrets via vault
- Storage Runtime: local provider, sha256 dedup, integrity check, file list/upload/delete
- Observability: execution query, per-action summary (success rate, avg, p95), health
- Realtime SSE: workspace event stream endpoint (GET /api/v1/v2/realtime/events)
- Phase 1 acceptance: core.health.check, core.user.create, core.user.list
- Actions: core.project.*, core.config.*, core.file.*, core.user.* (62 total)
