refactor: new design — sidecar services, moderator Gateway client, tool execute API

- Replace standalone no-reply-api Docker service with unified sidecar (services/main.mjs)
  that routes /no-reply/* and /moderator/* and starts/stops with openclaw-gateway
- Add moderator Discord Gateway client (services/moderator/index.mjs) for real-time
  MESSAGE_CREATE push instead of polling; notifies plugin via HTTP callback
- Add plugin HTTP routes (plugin/web/dirigent-api.ts) for moderator → plugin callbacks
  (wake-from-dormant, interrupt tail-match)
- Fix tool registration format: AgentTool requires execute: not handler:; factory form
  for tools needing ctx
- Rename no-reply-process.ts → sidecar-process.ts, startNoReplyApi → startSideCar
- Remove dead config fields from openclaw.plugin.json (humanList, agentList, listMode,
  channelPoliciesFile, endSymbols, waitIdentifier, multiMessage*, bypassUserIds, etc.)
- Rename noReplyPort → sideCarPort
- Remove docker-compose.yml, dev-up/down scripts, package-plugin.mjs, test-no-reply-api.mjs
- Update install.mjs: clean dist before build, copy services/, drop dead config writes
- Update README, Makefile, smoke script for new architecture
