feat: Add session workflow framework and complete first inbox zero

Created emacs-inbox-zero session definition and validated it by
executing the workflow. Processed 5 inbox items to zero in 10 minutes.

Session Framework:
- Created docs/sessions/ directory for session definitions
- Added create-session.org (meta-workflow for creating sessions)
- Added emacs-inbox-zero.org (weekly inbox processing workflow)
- Updated NOTES.org with terminology and session tracking

Inbox Zero Results:
- Deleted 1 duplicate task (chime fix)
- Moved 2 to Method 1: org-capture performance [#B], EMMS keybindings [#D]
- Moved 2 to someday-maybe: dashboard icons, persistence files
- Recognized perfectionism pattern (V2MOM Obstacle #4)

Learnings captured in living documents:
- Save Q&A answers incrementally during session creation
- Capture useful context during triage (impact estimates, theories)
- Validation by execution catches what theory misses

Files reorganized:
- Renamed docs files to UPPERCASE for consistency
- Removed SESSION-HANDOFF-ACTIVE-PROJECT.org (replaced by NOTES.org)

V2MOM Metrics fulfilled:
- Weekly triage consistency: ✓ (2025-11-01)
- Active todo count: 29 items (working toward < 20)
