chore(orchestrator): rescope Phase 7 as Feature Completion, add Phase 8

Phase 7 was underscoped as "Polish & Beta" but the platform isn't
feature-complete. Based on E2E testing feedback:

Phase 7 → "Feature Completion (v0.0.8)" with 17 tasks:
- 6 new web UI tasks (P7-009–P7-014): chat, conversations, projects,
  providers, settings, admin
- 3 agent tasks (P7-015–P7-017): tool expansion, MCP client, skills
- 2 CLI tasks (P7-018–P7-019): model switching, session management
- 1 architecture task (P7-020): coord DB migration

Phase 8 → "Polish & Beta (v0.1.0)" with deferred tasks:
- Additional SSO/LLM providers, performance, release gate

+### Session 11 (continued) — E2E testing + bug fixes + Phase 7 rescope
+
+**Bug fixes merged during E2E testing (PRs #107-#117):**
+
+- CI: from_secret syntax for Woodpecker v2 (#107)
+- Gateway: dotenv loading from monorepo root (#108)
+- Gateway: missing @Inject() decorators causing silent hang (#109)
+- Gateway: CORS + memory userId + pgvector auto-init (#110)
+- Auth: BetterAuth trustedOrigins for web dashboard (#111)
+- Auth: CORS headers on raw BetterAuth HTTP handler (#112)
+- Husky: removed deprecated v9 shim lines (#113)
+- CLI: login command + authenticated TUI sessions (#114)
+- CLI: Origin header on auth requests (#115)
+- Agent: Ollama provider registration with openai-completions API (#116, #117)
+
+**E2E testing results:**
+
+- Web UI: login works, projects list, chats list (but chat doesn't function)
+- TUI: authenticated connection works, agent responds via Ollama llama3.2
+- Agent tools: brain, coord, memory tools confirmed working
+- Gateway: all routes mapped, providers register correctly
+
+**Phase 7 rescoped (Jason directed):**
+
+- Phase 7 renamed from "Polish & Beta" to "Feature Completion (v0.0.8)"
+- Added 13 new tasks (P7-009 through P7-021): web UI, agent tools, CLI, coord architecture
+- P7-002 (extra SSO), P7-003 (extra LLM), P7-005 (perf), P7-008 (v0.1.0 tag) moved to Phase 8
+- Phase 8 added as "Polish & Beta (v0.1.0)"
+- Reason: platform isn't feature-complete enough for beta — web UI is scaffolded but non-functional for real use, agent tooling is minimal, CLI needs model switching
