openclaw update keeps failing

## How OpenClaw tries to update

 When you run (or the cron runs):

 - openclaw gateway update.run

 …the updater (implemented in that update-runner.ts) roughly does:

 1. Find the git repo root (your /Users/stv/openclaw)
 2. git fetch / check out the target tag/commit
 3. Install deps (pnpm install or whatever package manager it detects)
 4. Build (pnpm build)
 5. Build the Control UI assets (pnpm ui:build) → this generates dist/control-ui
 6. Then it does “restore control-ui”: git checkout -- dist/control-ui/
     - intention: UI build produces hashed assets and would leave the repo “dirty”, which would block future updates
     - so they try to reset that directory back to the committed state

 ### Why it keeps failing for you

 Because at the commit you’re on (57c34a32, ca47b0d7, etc.), git doesn’t know about dist/control-ui/ (not tracked / not present), so git checkout -- dist/control-ui/ errors and the whole update is marked
 failed.

 If you want, I can also point you to the exact line numbers in update-runner.ts and we can decide whether the right fix is:
 - make dist/control-ui tracked again (if that was intended), or
 - change the updater to not run that checkout when the path isn’t tracked.
