BREAKING CHANGE: Convert repository to IronClaw-only package with strict
external dependency on globally installed `openclaw` runtime.
### Changes
- Remove entire OpenClaw core source from repository (src/agents/*, src/acp/*,
src/commands/*, and related modules)
- Implement CLI delegation: non-bootstrap commands now delegate to global
`openclaw` binary via external contract
- Remove local OpenClaw path resolution from web app; always spawn global
`openclaw` binary instead of local scripts
- Rename package.json scripts: `pnpm openclaw` → `pnpm ironclaw`,
`openclaw:rpc` → `ironclaw:rpc`
- Update bootstrap flow to verify and install global OpenClaw when missing
- Migrate web workspace/profile logic to align with OpenClaw state paths
- Add migration contract tests for stream-json, session subscribe, and profile
resolution behaviors
- Update build/release pipeline for IronClaw-only artifacts
- Update documentation for new peer + global installation model
### Architecture
IronClaw is now strictly a frontend/UI/bootstrap layer:
- `npx ironclaw` bootstraps OpenClaw (if missing), runs guided onboarding
- IronClaw UI serves on localhost:3100
- OpenClaw Gateway runs on standard port 18789
- Communication via stable CLI contracts and Gateway WebSocket protocol only
### Migration
Users must have `openclaw` installed globally:
npm install -g openclaw
Existing IronClaw profiles and sessions remain compatible through gateway
protocol stability.
