Bump stale GitHub Actions versions (#2618)

## Summary

Bumps all stale GitHub Actions to their latest stable versions across 7
workflow files.

### Changes

| Workflow | Action | Old | New |
|---|---|---|---|
| `ci.yaml` | `astral-sh/setup-uv` | `@v8.0.0` / `@v7` (inline jobs
only) | `@v8.1.0` |
| `claude.yml` | `astral-sh/setup-uv` | `@v6` | `@v8.1.0` |
| `codeflash-aiservice.yaml` | `astral-sh/setup-uv` | `@v7` | `@v8.1.0`
|
| `codeflash-js.yaml` | `astral-sh/setup-uv` | `@v7` | `@v8.1.0` |
| `deploy_aiservice_to_azure.yml` | `astral-sh/setup-uv` | `@v7` |
`@v8.1.0` |
| `fix-formatting.yml` | `astral-sh/setup-uv` | `@v5` | `@v8.1.0` |
| `fix-formatting.yml` | `j178/prek-action` | `@v1` | `@v2` |
| `publish-to-pypi.yml` | `pypa/gh-action-pypi-publish` | `@master` |
`@release/v1` |

### Notes

- Shared workflow refs (`codeflash-ai/github-workflows/...@main`) in
`ci.yaml` are **not** changed -- those follow `@main` and will pick up
updates from the shared workflows repo.
- `publish-to-pypi.yml` is currently disabled (`if: false`) but the ref
is fixed anyway to avoid issues when re-enabled.

## Test plan

- [ ] CI passes on this PR (the workflow files themselves are the
change, so CI validates they parse correctly)
- [ ] Verify `ci.yaml` shared workflow `uses:` lines still reference
`@main`
