## Summary
- resolve the configured planning model when agent onboarding requests
omit an explicit override
- align the onboarding prompt with supported runtime/model hint fields,
allowing AI-created agents to select runtimes such as Hermes
- refresh the generated GitHub issue import limits required by the
repository sync gate
## Root cause
The agent onboarding route loaded project settings but passed only
request-body model fields. The AI Interview UI omits those fields, so
`createFnAgent` was called with `provider=undefined, model=undefined`;
the session returned no usable assistant JSON. The prompt catalog also
prohibited `runtimeHint` despite the parser and form already supporting
it.
## Verification
- targeted agent onboarding tests: 22 passed
- `pnpm --filter @fusion/core typecheck`
- `pnpm --filter @fusion/dashboard typecheck`
- `pnpm lint`
- `pnpm build`
- `pnpm smoke:boot`
- engine merge-gate subset: 294 passed
Full `pnpm test` reached the PostgreSQL gate but this host has no `psql`
binary, so 23 PostgreSQL suites could not start; this is an environment
prerequisite failure, not a test assertion failure.

## Summary by CodeRabbit
* **Bug Fixes**
* Agent onboarding interviews now use the configured planning model when
no override is provided.
* Runtime suggestions and runtime-hint guidance are preserved during
onboarding and reflected in generated configurations.
* On onboarding start streaming, planning provider/model resolution now
comes from settings with stricter override validation, and test mode
continues to take priority.
* **Documentation**
* Updated onboarding prompt guidance to support additional configuration
fields and optional runtime draft hints.
* Reduced the maximum GitHub issue import/browse limit from 100 to 50.
* **Tests**
* Added coverage for runtime-hints prompting and planning-model override
behavior.
