Kpa-clawbot 9f14c74b3e ci: add Docker cleanup before build to prevent disk space exhaustion (#473) ...

## Summary

Fixes #472

The Docker build job on the self-hosted runner fails with `no space left
on device` because Docker build cache and Go module downloads accumulate
between runs. The existing cleanup (line ~330) runs in the **deploy**
step *after* the build — too late to help.

## Changes

- Added a "Free disk space" step at the start of the build job,
**before** "Build Go Docker image":
- `docker system prune -af` — removes all unused images, containers,
networks
  - `docker builder prune -af` — clears the build cache
  - `df -h /` — logs available disk space for visibility
- Kept the existing post-deploy cleanup as belt-and-suspenders
