Marketplace branding; trim internal notes

[buildpulser]

Adds author and branding (icon and color), which the GitHub Marketplace requires, and rewords one line of the description. Also trims comments and a README status note that referenced internal tickets and cost figures. Comment-only in src: npm test passes and a rebuild leaves dist/ unchanged.

Agent code review

Walkthrough

This PR makes two categories of changes: (1) adds author and branding metadata fields to action.yml for GitHub Marketplace presentation, and fixes a minor wording nit in the description; (2) strips internal references (ticket numbers like runners#72 / runners#74 and specific internal cost metrics like 3.8M Tier1 requests, 12.8GB vs ~3GB, 83% of S3 bill) from comments in src/post.js and src/refresh-policy.js. No functional logic is changed — every diff hunk is either metadata or a comment.

Findings

No issues found.

Verdict

All changes are documentation/metadata only: GitHub Action branding fields and comment cleanup that removes internal ticket references and internal cost metrics from public-facing source files. No logic is touched, no tests are weakened, and there are no auto-merge red flags. Clean diff — safe to merge.

Confidence

HIGH — all three changed files were read in full; the diff is exclusively comments and action metadata.

💡 Tips for working with the BuildPulse reviewer

• Re-review on demand — comment @buildpulse review on the PR (/buildpulse review also works). The fresh review bills the requester's seat.
• Teach it by replying to a finding — reply to any inline comment: "we never do X here" becomes a standing rule for this repository (acknowledged in-thread, not raised again); "not in this PR" mutes the topic for this PR only. Replies are free. Org admins can view or remove learned rules on the AI Features page.
• Every push is re-reviewed automatically — smaller PRs get a fresh full review, larger ones get a delta review of what changed since the last look; an "Update branch" merge with an unchanged diff carries the previous verdict forward without a new billed review.
• Draft PRs are skipped until marked ready for review (repositories can opt in to draft reviews on the AI Features page).
