The /workspace compatibility symlink was removed from the manifest
compiler/entrypoint in 3e59a25. Tool definitions that still set
runtime.working_dir to /workspace therefore start in an empty directory
instead of /home/user/{repo_name}.
- manifest-editor.tsx: default working_dir to empty instead of /workspace;
update startup-script placeholder to reference /home/alex/.
- Add Alembic migration 2026_06_19_113000 that clears the stale
runtime.working_dir = /workspace from the built-in pi-agent manifest.
- Add migration import test.
