feat(system): seedgo v2 operational, full system audit, 14/15 branches at 99%

Three days of intensive work bringing seedgo to full operational status
and driving all branches through comprehensive standards compliance.

Seedgo v2.0.0:
- 22 checkers active (up from 20), standards pack fully operational
- New introspection standard researched from Dev-Pass, FPLAN-0017 open
- Bypass system for false positives (.seedgo config)
- Standards query and audit commands fully functional

System-wide audit (FPLAN-0016):
- All 14 auditable branches at 99%+ compliance
- CLI imports standardized across all branches (console from cli.apps.modules)
- handle_command(command, args) → bool contract added to all modules
- print_help() function naming fixed for checker pattern matching
- Handler extraction: large modules split, file I/O moved to handler layer
- New handlers created across ai_mail, backup, daemon, flow, skills, spawn, seedgo

Branch-specific highlights:
- ai_mail: email.py split 840→420 lines, 4 new handlers
- flow: dplan_flow.py 688→591 lines, 4 new handlers
- seedgo: massive restructure — standards moved to handlers/aipass_standards/,
  old standards/ tree removed, bypass system added, diagnostics module
- commons: database module added, CLI imports fixed
- skills: 5 handle_commands added, help function renamed
- trigger: error reporter handler, handle_command routing
- All branches: consistent architecture, clean drone routing

Culture doc (CLAUDE.md) added — documents AIPass philosophy, identity,
memory system, and collaboration principles.
