act_runner containers share /tmp across jobs. setup-uv writes its wheel cache to /tmp/setup-uv-cache by default, which fills the partition and breaks subsequent runs with:

No space left on device (os error 28)

Caching is useless on ephemeral runners anyway — the cache directory is discarded when the container exits. Disabling it avoids the disk-pressure regression without adding download time (the uv binary is already pinned to a direct download URL, and each job only installs dependencies once).

Fixes #17

Test plan: next push to main should run Tests/test and Tests/e2e without writing to /tmp/setup-uv-cache. Monitor runner disk usage to confirm no "No space left on device" errors.
