* fix: resolve stdio transport race condition for concurrent tool calls

Fixes #528 by replacing goroutine-per-request pattern with a worker pool
to prevent multiple goroutines from accessing the non-thread-safe bufio.Reader.

- Add worker pool pattern with configurable size (default: 5 workers)
- Add buffered queue for tool calls (default: 100 capacity)
- Protect concurrent writes with mutex
- Maintain backward compatibility while fixing the race condition
- Add comprehensive test for concurrent tool calls

* refactor: remove redundant mutex around thread-safe sync.Map

sync.Map is already thread-safe and doesn't require additional mutex protection.
This simplifies the test code while maintaining the same functionality.

* refactor: improve test control flow and add configuration bounds validation

- Replace goto statements with labeled break for more idiomatic Go
- Reduce test timeout from 5s to 2s for faster test execution
- Add upper bounds validation for worker pool size (max 100) and queue size (max 10000)
- Add tests to verify configuration bounds are respected
- Log warnings when configuration values exceed maximum limits

Addresses remaining CodeRabbit review feedback.

* fix: use maximum values instead of defaults when limits exceeded

When WithWorkerPoolSize or WithQueueSize receive values exceeding their
maximum limits, use the maximum allowed value instead of falling back
to the default. This better aligns with user expectations when they
request large pool/queue sizes.

* test: update stdio tests to expect maximum values when limits exceeded

Update test expectations to match the new behavior where WithWorkerPoolSize
and WithQueueSize use maximum values instead of defaults when the requested
size exceeds limits.
