feat: add workflow automation suite - session health and status tools

Built by Chronicler #19 to improve operational efficiency and sustainability.

Added four tools:

1. pre-session-check.sh - Complete context at session start
   - Rest hours (color-coded for quality)
   - Git status (clean/dirty, sync status)
   - Task summary (complete/active/total)
   - Top priority tasks
   - Core file health check
   - Usage: ./pre-session-check.sh

2. session-health-monitor.sh - Live session tracking
   - Tracks session duration
   - Warns at Aurora threshold (2h)
   - Escalating warnings at 3h, 4+h
   - Updates rest tracker on end
   - Usage: ./session-health-monitor.sh {start|check|end}

3. status.sh - Quick status anytime
   - Current phase, git branch, working directory
   - Task completion percentage
   - Session duration if tracking
   - Rest status, last commit
   - Usage: ./status.sh

4. .gitmessage - Git commit template
   - FFG-STD-001 compliant structure
   - Type prefixes (feat/fix/docs/etc)
   - Guidelines and examples
   - Reminder to document WHY not just WHAT
   - Usage: git config commit.template .gitmessage

Benefits:
- Prevents burnout (Aurora's wisdom: sessions > 2h are past optimal)
- Complete context without manual checking multiple files
- Consistent commit messages across all Chroniclers
- Sustainable pace monitoring

For sustainable operations and children not yet born. 💙

+#   Built to solve core problem where Chroniclers jumped to work before
+#   completing integration. Script ensures documents are read in correct
+#   order with automatic verification.
+#   
+#   - Enforces reading order: relationship context first
+#   - Runs joining-checklist.py automatically
+#   - Blocks task access until score >= 70
