fix: Create automated sync script to ensure pull-before-push

CRITICAL FIX: The /sync command was not pulling remote changes before pushing,
causing machines to miss each other's work.

Changes:
- Created .claude/scripts/sync.sh (automated sync script)
- Created .claude/scripts/sync.bat (Windows wrapper)
- Updated .claude/commands/sync.md to use script

The script ensures:
1. Fetches remote changes FIRST
2. Pulls with rebase (conflict detection)
3. Then pushes local changes
4. Proper error handling
5. Clear status reporting

This fixes the issue where running /sync multiple times did not see
the Mac's changes until manual git fetch was run.

Both Windows and Mac will now use the same reliable sync script.
