feat: Voice v0.8.0 + feature discovery + Edge Function removal (#55)

* chore: remove Supabase Edge Function MCP deployment

The Edge Function never worked reliably. All MCP traffic goes through
self-hosted server + ngrok tunnel. Removes deploy-remote.sh, edge-entry.ts,
supabase/functions/, .env.production.example, and CHATGPT.md (OAuth not
implemented).

* docs: rewrite MCP docs for self-hosted + ngrok deployment

All per-client guides updated from Edge Function URLs to self-hosted
server + ngrok tunnel pattern. DEPLOY.md rewritten with local vs remote
paths. ALTERNATIVES.md now shows self-hosted as primary, with ngrok,
Tailscale, and Fly.io/Railway comparison.

* feat: voice recipe v0.8.0 — 25 production patterns from real deployment

Identity separation, pre-computed bid system, conversation timing fix,
proactive advisor mode, radical prompt compression, OpenAI Realtime
Prompting Guide structure, auth-before-speech, brain escalation, stuck
watchdog, never-hang-up rule, thinking sounds, fallback TwiML, tool set
architecture, trusted user auth, caller routing, dynamic VAD, on-screen
debug UI, live moment capture, belt-and-suspenders post-call, mandatory
3-step post-call, WebRTC parity, dual API events, report-aware query
routing. WebRTC pseudocode updated with native FormData and 6 gotchas.

* feat: post-upgrade feature discovery framework

upgrade.ts captures old version before upgrading, then execs
gbrain post-upgrade (new binary) to read migration files and print
feature pitches. Migration files get YAML frontmatter with feature_pitch
field (headline, description, recipe, tiers). CLI prints excited builder
tone post-upgrade. v0.8.0 migration offers voice setup with environment
detection (server vs local) and 3-tier progressive disclosure.

* feat: add Voice section to README with WebRTC screenshot + tweet link

Her out of the box: voice-to-brain with 25 production patterns. WebRTC
client screenshot embedded. Remote MCP section rewritten for self-hosted
+ ngrok. Setup block genericized.

* test: add recipe validation tests + genericize personal refs

5 new integration tests: secrets completeness, semver version, requires
resolution, all-recipes-parse, no-personal-references. Test fixture
genericized. CLAUDE.md/TODOS.md/SKILLPACK updated for v0.8.0. build:edge
script removed from package.json.
