Add manifest-driven OpenAPI client sync action

[lightsofapollo]

Summary

• add openapi-to-rust clients check|update|sync for manifest-driven client generation
• support checked-in and remote OpenAPI specifications, including vendoring and normalization
• compile and optionally test generated clients
• add a composite GitHub Action that can report drift or submit update PRs
• publish checksummed prebuilt CLI archives for Linux, macOS, and Windows
• add CI fixtures, documentation, and release tooling

Why

Client repositories need one consistent workflow for validating checked-in generated code and automatically tracking remote API specifications. Keeping this in the existing generator avoids introducing a second CLI while making the full flow reusable from GitHub Actions.

Impact

Consumers can use check mode for manually maintained internal specifications, or scheduled sync mode for remote specifications such as Runpod API v2. The action reports detected changes and can create normal or draft update PRs depending on validation results.

Validation

• cargo test --all-features
• cargo fmt --all -- --check
• cargo clippy --all-features -- -D warnings
• RUSTDOCFLAGS="-D warnings" cargo doc --no-deps --all-features
• cargo check --no-default-features
• actionlint .github/workflows/ci.yml .github/workflows/publish.yml
• release packaging/checksum smoke test
• composite action success and failure smoke tests
• installer smoke test
