S56: spawn template overhaul + system-wide README push + .gitkeep cleanup (#129)

- Spawn template system rebuilt: regenerate-registry command (3-pass ID matching),
  registry 26→41 files, generate_branch_meta fixed, Phase 0 snapshot added
- System-wide push: 12/12 branches updated (227 additions, 0 errors)
- READMEs added to all standard directories across 15 branches
- .claude/settings.local.json tracked system-wide (deny rules)
- 35 .gitkeep files removed (replaced by READMEs)
- Bypass files updated across 13 branches
- Bugs fixed: manager citizen_class crash, backup rglob performance
