Add mizan-ts: TypeScript backend adapter proving AFI is language-agnostic

The TypeScript adapter produces the same manifest, the same
X-Mizan-Invalidate headers, the same JSON invalidation protocol,
and the same CDN-ready response headers as mizan-django.

One Edge Worker. Two backend languages. Same protocol.

Features:
- @client decorator (function wrapper + class method decorator)
- ReactContext class (same API as Django adapter)
- Registry with context groups and param tracking
- Context bundled GET: /api/mizan/ctx/<name>/
- Mutation POST: /api/mizan/call/ with server-driven invalidation
- Three-tier auto-scoping (argument name matching → broad fallback)
- Function-level affects targeting
- private=True (rejected from RPC, in manifest for Edge)
- X-Mizan-Invalidate header with URL-encoded params
- Edge manifest generation (identical format to Django's)
- render_strategy + user_scoped derivation

22 edge compatibility tests pass (Bun, 21ms):
- Deterministic JSON, sorted keys
- Cache-Control: public on GETs, no-store on mutations/errors
- Vary: Authorization, Cookie
- Header round-trip with special characters
- Auto-scoped invalidation matches body and header
- Function-level invalidation
- Private function rejection
- Manifest structure with PSR/dynamic_cached strategies
