chore(action): fix Marketplace listing name and add author

[uipreliga]

Unblocks publishing the composite action to the GitHub Actions Marketplace.

Why

Publishing action.yml to the Marketplace fails with:

coder-eval - Name must be unique. Cannot match an existing action, user or organization name.

The Marketplace name must be globally unique across actions, users, and organizations — not just actions. github.com/coder-eval is an unrelated organization (created 2023-12-04, 1 public repo, no display name) squatting the name, so name: coder-eval can never be published as-is.

This was the last blocker on the listing. The prerequisite that previously blocked it — zero published Releases — was cleared by v0.9.0–v0.9.3.

What changed

• name: coder-eval → name: coder_eval. Verified free as a Marketplace slug and as a GitHub user/org name.
• author: UiPath added — Marketplace surfaces it on the listing and it was previously absent. Matches the authorship the project already declares in pyproject.toml (authors = [{ name = "UiPath", ... }]) and NOTICE (© 2026 UiPath), and the repo owner that Marketplace derives “By UiPath” from.
• Comments recording why each value is what it is, so a future cleanup does not silently re-break the publish.

Not a breaking change

name is display-only. Consumers reference the action by repo path:

- uses: UiPath/coder_eval@v0

That path is unaffected. I searched the repo for Marketplace listing URLs (marketplace/actions/…) — there are none — and no README badge or doc names the action, so no docs, tutorials, or workflow examples need updating. Deliberately not touched: coder-eval is also the CLI command (coder-eval run) and the PyPI package (pip install coder-eval), neither of which changes.

Follow-up required after merge

Merging alone does not make the new name live. v0 is force-moved to a release by release.yml, not by a merge to main, so @v0 will keep serving name: coder-eval until a release is cut. Sequence:

1. Merge this PR.
2. Let release.yml cut 0.9.4.
3. Publish to Marketplace from the 0.9.4 release (a manual, one-time web-UI step — gh release create cannot tick the checkbox; every subsequent release then lists automatically).

If GitHub normalizes _ → - in that uniqueness check, coder_eval will be rejected against the same squatted org. coder-eval-ci-gate is verified free as the fallback.

Verification

• action.yml parses; name, author, description, branding, runs.using: composite, all 10 inputs and both outputs (run-dir, junit-path) intact.
• Names checked against both github.com/<name> and github.com/marketplace/actions/<name>.
