fix(release): publish prefill-router before switchyard-runner

[nachiketb-nvidia]

What

• Publish prefill-router before switchyard-runner in the Rust release job.
• Validate its version against the release tag with the other published crates.
• Document the complete seven-crate publication order and token requirement.

Why

switchyard-runner has a versioned optional dependency on prefill-router. Cargo resolves that dependency while preparing the package even when the feature is disabled. The release job omitted the dependency, so runner publication stopped and switchyard-server could not be published afterward.

How

The existing idempotent publish_crate helper now publishes prefill-router after its library dependencies and waits for it to reach the crates.io index before publishing switchyard-runner. Existing versions are still skipped.

Validation

• cargo package --locked -p prefill-router --no-verify
• prefill-router packaged 14 required files successfully.
• actionlint passed for .github/workflows/publish.yml.
• Repository pre-commit hooks passed.
• No crate was published and no tag was created.

Fixes SWITCH-1444.

Summary by CodeRabbit

• Release Process
  • The release workflow now validates and publishes the prefill-router crate in dependency order.
  • The release process now covers seven crates, and the configured crates.io token must authorize publishing all of them.
