feat: wire up all Phase 2-6 features into daemon and config

Integrate all new features into the shared infrastructure:
- Config schema: add memory, discord, slack, process, web_search schemas
- Daemon wiring: memory store init, tool registration, channel adapters
- Orchestrator: memory injection into system prompt, extraction on compaction
- Agent: add setSystemPrompt() for dynamic prompt updates
- Channel/tool index: export new adapters and tool factories
- Add @slack/bolt, discord.js, turndown, linkedom, @mozilla/readability deps
- Update state.json with Phase 3b completion (494 tests passing)
