docs: add branch cleanup audit

[ProfRandom92]

Summary:

• Add docs/reports/branch-cleanup-audit.md containing a snapshot inventory of visible branches, classification buckets (likely safe-delete, manual-review, keep), commented-out gh delete template for safe-delete candidates, and an explicit note that no branches or PRs were modified.

Changed files:

• docs/reports/branch-cleanup-audit.md

Testing:

• Ran python scripts/run_checks.py which completed and wrote docs/reports/check-report.md.
• Verified branch visibility with git branch -a --no-color which showed only the work branch, and checked workspace state with git status --short.

Risks:

• The audit reflects only the local repository snapshot and may omit remote or freshly-fetched branches, so safe-delete candidates could change after fetching remotes.

Next:

• Regenerate the audit if additional remotes/branches are fetched to reassess safe-delete and manual-review candidates.

Code Review

This pull request introduces a new documentation file, docs/reports/branch-cleanup-audit.md, which provides an audit of local repository branches and identifies candidates for deletion. The review feedback suggests improving the syntax of the included GitHub CLI command by using {owner} and {repo} placeholders for automatic interpolation, which reduces the need for manual editing.

[gemini-code-assist]

The gh CLI automatically interpolates {owner} and {repo} from the current repository context. Using these placeholders instead of :owner and :repo allows the command to be executed with less manual editing and fewer errors.

	# gh api repos/{owner}/{repo}/git/refs/heads/<branch> -X DELETE
