v0.3.0 release

Breaking Change!

This release is NOT compatible with v0.2.x. Existing encrypted indexes must be re-created.
Embedding dimension changed from 768 to 1024: Default embedding model switched from bge-base-en-v1.5 (768d, English-only) to Qwen3-Embedding-0.6B (1024d, multilingual). All previously encrypted vector data is incompatible with this version. There is no automatic migration — indexes must be rebuilt from source with the new model.
Accordingly, the rune-vault should be upgraded to v0.3.0. Please find https://github.com/CryptoLabInc/rune-admin/releases/tag/v0.3.0.
