feat: port OpenClaw bidirectional integration from omx

Ports the complete OpenClaw integration system from oh-my-codex:

Outbound (opencode→OpenClaw):
- wakeOpenClaw() fire-and-forget gateway notifications
- HTTP and command gateway dispatchers
- Template variable interpolation
- Config from oh-my-opencode.jsonc (no env gate needed)

Inbound (OpenClaw→opencode):
- Reply listener daemon (Discord/Telegram polling)
- Session registry for message↔tmux pane correlation
- Tmux pane detection, content capture, and text injection
- Input sanitization and rate limiting
- Pane verification before injection

Files:
- src/openclaw/ (types, config, dispatcher, index, reply-listener, session-registry, tmux, daemon)
- src/config/schema/openclaw.ts (Zod v4 schema)
- src/hooks/openclaw.ts (session hook)
- Tests: 12 pass (config + dispatcher)
