fix: deterministic TypeScript type generation for run-config.ts (#194)

## Summary

The `typescript_generation` test in CI was flaky due to
non-deterministic ordering of type declarations in `run-config.ts`.

### Root cause

`ts_rs::visit_dependencies` traverses type dependencies using a
`HashMap` internally, so the visitation order of sibling types (e.g.
`UserGlobalCacheConfig` vs `Task`) varies between runs. This caused
`generate_ts_definition()` to emit declarations in a random order,
making the test pass or fail depending on whether the output happened to
match the checked-in file.

### Fix

- Sort the collected type declarations alphabetically before emitting
them, ensuring deterministic output regardless of `HashMap` iteration
order
- Regenerate `run-config.ts` with the now-stable ordering

Verified stable across 20 consecutive regenerations.
