[Store][ChromaDb] Split ChromaDb store as dedicated package

OskarStark · OskarStark · commit 9792e95519ac · 2025-12-05T18:27:56.000+01:00
Similar to how tools were split in the Agent component, this extracts the ChromaDb store into its own standalone package with:
- Independent composer.json with proper dependencies
- Dedicated test suite with phpunit.xml.dist
- Standard package files (LICENSE, README.md, CHANGELOG.md)
- GitHub integration files for subtree split workflow
