Pull request overview

This PR adds a new code generation mode to oapi-codegen that emits a blocking reqwest client from the same lowered Service IR used by the axum server generator, along with new fixtures/snapshot outputs and coverage harness updates to validate the generated client output.

Changes:

• Introduces a new generate.client config knob and wires it through CLI/config plumbing to emit a blocking reqwest client.
• Adds a new emit/reqwest.rs client emitter (typed responses, per-op methods, and an operation-shape rejection gate).
• Extends the test/coverage framework with client fixtures, a committed generated client snapshot, and compile/runtime checks.
