chore(maintenance): branch-cleanup inventory + gitignore for ephemeral lists

[alrimarleskovar]

Summary

Two housekeeping items bundled:

1. .gitignore update — add .cleanup-branches-*.txt so future locally-generated ephemeral inventories don't trip the stop-hook untracked-files check.

2. scripts/maintenance/branch-cleanup-2026-05-17.txt — tracked inventory of 304 remote branches safe to delete (post wave-5 doc refresh). Composition:

Class	Count	Notes
Squash-merge orphans (PR merged)	261	Git --merged misses these because squash rewrites commit hashes
Truly merged (Git-detectable)	37	Reachable from main HEAD via --merged main
PR closed without merging	2	claude/video-pitch-script (#183), fix/anchor-idl-build-payload-newtype (#358)
No-PR historical (absorbed/abandoned)	4	riptide-spike, tests-mocha-tsx-loader, setup-copilot-api-config, web3-security-audit
Total	304

Excluded from this list (KEEP): 11 OPEN PRs (7 dependabot + #319, #280, #279, #357), claude/implement-roundfi-desktop-SRV6l (session branch), main, plus 1 RESCUE candidate: chore/protocol-config-decoder-helper contains unique unmerged work (scripts/devnet/dump-protocol-config.ts — 304-line ProtocolConfig PDA decoder useful for the pre-Fase-5 realloc diagnostic that surfaced in the 2026-05-16 Squads rehearsal).

3. scripts/maintenance/README.md — usage doc with the run command + retirement policy.

Methodology: cross-referenced 279 --no-merged remote branches against 347 paged GitHub PRs to identify squash-merge orphans. Classification breakdown in the README.

How to run

cd ~/RoundFinancial
git pull origin main
xargs -L1 git push origin --delete < scripts/maintenance/branch-cleanup-2026-05-17.txt

Expected result: remote branch count 317 → 13.

Test plan

• wc -l scripts/maintenance/branch-cleanup-2026-05-17.txt = 304
• After running the deletion, git fetch --prune && git branch -r | wc -l ≈ 13
• .gitignore covers future .cleanup-branches-*.txt patterns
