Update all documentation - Phase 2 integration complete

Documentation updates reflecting 90% completion status:

README.adoc:
- Updated project status table (all components ✅ complete)
- Added total implementation stats (2,770+ lines ReScript)
- Updated language policy (ReScript, not TypeScript)
- Updated project structure to match actual files
- Corrected component status and line counts

ROADMAP.adoc:
- Marked Phase 3 (Edge Shield) as 90% complete
- Updated foundation and API gateway checklists
- Updated version milestones (v0.2.0 current)
- Listed completed features with line counts

META.scm:
- Added 5 ADRs (architecture decision records)
- Documented design rationale (why ReScript, Deno, Hono, MCP)
- Updated version to 0.2.0-rc1
- Added development practices

STATE.scm (new):
- Project state tracking
- 6 milestones (4 complete, 1 in-progress, 1 planned)
- Current blockers and issues
- Critical next actions
- Session history (2026-01-25)
- Helper functions for querying state

ECOSYSTEM.scm (new):
- Svalinn's position in verified container ecosystem
- Relationships to Vörðr, Cerro Torre, verified-container-spec
- Integration status with dependencies
- What Svalinn is/is not

Session summary:
- 13 commits made
- 3 integration gaps fixed (routes, validation, policy)
- 198 lines deprecated code removed
- 2,770+ lines production ReScript code
- Deployment readiness: 80% → 90%
