⬆️ Bump GitHub Actions, drop unmaintained action-clean (#64)

* ⬆️ Bump GitHub Actions to latest versions

- actions/checkout v4 → v6
- AutoModality/action-clean v1.1.0 → v1.1.1
- astral-sh/setup-uv v4 → v8.1.0 (no major tag — v8 stopped publishing them)

prewk/s3-cp-action already pinned at major v2.

actions/checkout v6 needs runner ≥ 2.329.0; the ce-ci packer config
pins runner_version = "2.330.0", so self-hosted runners are clear.

* Revert action-clean v1.1.1 — upstream is broken (rm -rf ..)

Smoke-tested with workflow_dispatch on tinycc and the clean step
failed: v1.1.1 changed entrypoint.sh from 'rm -rf *' to 'rm -rf ..',
which rm refuses. Sticking with v1.1.0; checkout@v6 and
setup-uv@v8.1.0 stay.

* Drop AutoModality/action-clean for inline find -delete

The action's upstream is unmaintained (last release years ago, and
v1.1.1 shipped a literal 'rm -rf ..' regression). Replacing with the
same pattern infra/ uses elsewhere:

    sudo find \"\$GITHUB_WORKSPACE\" -mindepth 1 -delete

sudo is needed because the docker builds produce root-owned output.
