gsxdsm 130f6f1e9a FN-5834: enforce explicit developer-role compatibility for custom providers

Prevent unsupported developer-role API failures by making provider role compatibility explicit and covered by regression safeguards.

- Add explicit supportsDeveloperRole capability to custom provider metadata/types and wire it through provider registration.
- Update CLI custom-provider registration behavior and tests to persist and validate developer-role compatibility settings.
- Add/adjust engine regression coverage for openai-completions message role conversion, including reasoning-model fallback behavior.
- Document the new custom provider setting and add a published changeset for @runfusion/fusion.
