Pull request overview

This PR addresses the promotion-review follow-ups by tightening the devcontainer uv warm-up behavior, correcting the workflow snippet catalog description, and completing the PyPI caller example with artifact cleanup after publish.

Changes:

• Gate the devcontainer uv warm-up to locked Python projects by requiring uv.lock, and run uv sync in frozen mode.
• Update the workflow snippet catalog description to reflect that the hub .github/workflows/ contains both entry points and reusable tasks.
• Extend the PyPI publish caller example to delete the consumed build artifact and add the required actions: write permission.

• Agent-authored prose convention prohibits mid-sentence semicolons (see .agents/skills/comment-and-doc-style/SKILL.md:171-173). This warning message uses a semicolon, which will violate that convention in any lint that checks emitted/logged prose.

 echo "::warning::Failed to delete artifact $id; retention-days backstop will reap it."

Addressed the one suppressed finding from 85ce8c3 in b1ffb83. The warning for a failed artifact deletion now uses two sentences instead of a mid-sentence semicolon; the sibling artifact-listing warning was corrected in the same commit.
