FPLAN-0410 repo cleanup + integration test bug fixes

VERA cleanup (FPLAN-0410):
- Remove all /home/aipass hardcoded paths (portability)
- Remove internal Telegram bot code from public repo (6k+ lines)
- Remove runtime logs, .claude/settings.local.json, stale files
- Clean READMEs across all branches
- Restructure spawn handlers into proper 3-layer architecture
- Add __init__.py files for proper package imports
- Update seedgo standards for public repo context
- Add log_structure standard to seedgo

Integration test bug fixes:
- Fix double @@ display in drone introspection output
- Fix spawn registry resolving to wrong file (walk up from package root)
- Fix email sender identity always showing as @ai_mail (pass AIPASS_CALLER_CWD)
- Fix branch_detection.py relative path resolution against CWD instead of registry dir
- Add .trinity/passport.json detection for spawned agents
- Archive duplicate json_ops.py, update imports to canonical json_handler
- Update .gitignore for runtime logs and .claude/ dirs

Tested end-to-end in Docker container (aipass-test:latest):
- Spawn → register → send email → receive → reply all verified working
