Add a new `bump` script at the repository root that updates version
constraints for all symfony/ai-* dependencies across the monorepo.
Features:
- Accepts version constraint as argument (e.g., ^0.1, ~0.1.0, @dev)
- Scans src/, demo/, and examples/ directories for composer.json files
- Updates symfony/ai-* packages in both require and require-dev sections
- Provides helpful CLI output showing all applied changes
- Shows summary with total updates and next steps
Usage:
./bump ^0.1
./bump @dev
Similar to the existing `link` script, this tool helps maintain
consistent versioning across all components during releases.
