fix(system): S61-S62 — API cleanup, drone path routing, naming checker, .backup→.recovery rename (#142)
- API: 18-item P0/P1/P2 cleanup (debug prints→logger, help gate fix, URL injection fix, key masking, unused imports)
- Drone: passport walk-up replaces hardcoded src/aipass/<branch> pattern, 13 naming bypasses removed
- Seedgo: naming checker fixed (__dunder__ skip + column-0 scope detection) — eliminates 71 false positives system-wide
- Spawn: .backup→.recovery rename (pre-change snapshots no longer conflict with backup branch namespace)
- .gitignore: .recovery/ added
- HERALD.md: Updated through S62 (backup audit, .recovery rename, night shift launch)
- README.md: Stats updated (141 PRs, 2900+ tests)
