feat(cli): M-Tool 1-3 — CLI, templates, Gitea publishing pipeline

Phase B complete: Shade now has a full developer tooling story.

@shade/cli
- shade init with project scaffolding from templates
- shade fingerprint (own or peer)
- shade publish (re-upload bundle)
- shade rotate (--identity for full rotation, otherwise signed prekey)
- shade peer add/list/verify/remove
- shade dashboard (opens observer in browser)
- shade doctor (diagnose config, storage, prekey server reachability)
- Config from .shaderc.json or SHADE_* env vars

Templates (in packages/shade-cli/templates/)
- bun-server — Bun + Hono backend with /send + /receive endpoints
- chat-demo — Two-process Alice/Bob chat over HTTP

Publishing pipeline (Gitea npm registry)
- .gitea/workflows/test.yml — CI on push/PR with PostgreSQL service
- .gitea/workflows/publish.yml — publish on git tag v*
- scripts/publish-all.ts — local publish helper with DRY_RUN support
- scripts/bump-version.ts — lockstep version bump across all packages
- Root package.json scripts: version, publish:dry, publish:all

Also: /health endpoint now lives in createPrekeyRoutes so doctor can
probe it without needing the full standalone setup.

Dry-run verified: all 11 packages pack cleanly.
246 tests passing, 0 failures.
