## Summary

- clamp parsed `Retry-After` and `Retry-After-Ms` delays to
`Duration.ZERO` when they are negative
- preserve immediate retries for past HTTP-date values
- add sync and async regression coverage for negative numeric delays and
past dates

Fixes #853

## Testing

- `git diff --check` passed
- direct ktfmt 0.61 validation passed for both changed Kotlin files
- full Gradle test suite was attempted online and offline; the online
run timed out during Kotlin/Gradle execution without diagnostics, while
the offline run was blocked by uncached `junit-jupiter-engine:5.9.3`
- repository lint tasks were attempted; direct ktfmt passed, while
Gradle lint was blocked by the same local dependency/compile environment

## Summary

Raise the custom-code budget from 2,000 to 3,000 lines to provide
headroom for the upcoming release. Current main uses 1,906 lines.
Generator cleanup will follow separately so it does not block the
release.

This PR changes only `.castiron-ratchet.json`.

- Add Live API endpoints.
