feat: Add /wrap-it-up slash command and phrase recognition

Created comprehensive session wrap-up workflow triggered by:
- Slash command: /wrap-it-up
- Phrases: "let's wrap it up", "that's a wrap", "let's call it a wrap"

Workflow:
1. Write session notes to docs/NOTES.org (decisions, work, context)
2. Git commit and push all changes to all remotes
3. Friendly goodbye summary with accomplishments and reminders

Added dual documentation:
- .claude/commands/wrap-it-up.md for explicit /wrap-it-up command
- docs/NOTES.org terminology section for phrase recognition

Makes session endings consistent and ensures no work is lost.
