Jason Woltje 56b644e6d3 feat: add mosaic upgrade command to clean stale per-project files
Detects and cleans up files that are now centralized:
- SOUL.md: removed (now global at ~/.config/mosaic/SOUL.md)
- CLAUDE.md: replaced with thin pointer to global AGENTS.md
- AGENTS.md: stale load-order sections stripped, project content preserved

Supports --dry-run, --all (scan ~/src/*), and per-project paths.
Creates .mosaic-bak backups before any modification.

mosaic-upgrade — Clean up stale per-project files
Usage:
mosaic-upgrade [path] Upgrade a specific project (default: cwd)
mosaic-upgrade --all Scan ~/src/* for all git projects
mosaic-upgrade --dry-run Preview changes without writing
mosaic-upgrade --all --dry-run Preview all projects
After Mosaic centralization:
SOUL.md → Removed (now global at ~/.config/mosaic/SOUL.md)
CLAUDE.md → Replaced with thin pointer or removed
AGENTS.md → Stale load-order sections stripped; project content preserved
