v0.6.0 — self-hosted local provider

Adds the self-hosted local OpenAI-compatible provider (#44).

v0.5.2

First release published via OIDC trusted publishing — no npm token involved.

• repository.url normalized to git+https:// (npm pkg fix), silencing the warning npm emitted on every publish.
• Proves the publish.yml path end-to-end: 0.5.1 was published manually because npm cannot configure a trusted publisher for a package that does not yet exist.

Expect a build provenance attestation on this version; 0.5.1 has none.
