- plugins/macp/src/index.ts: updated OC SDK imports to local paths
- plugins/macp/src/macp-runtime.ts: DEFAULT_REPO_ROOT → mosaic-stack-new, PI_RUNNER_PATH updated
- plugins/macp/openclaw.plugin.json: default repoRoot description updated
- Removed stale tsconfig.tsbuildinfo with old path references
