v1.13.0

What's Changed

Migrated the runtime to Falcon's fiber-driven async stack with non-blocking caching and adopted html2rss's native HTTPX transport, delivering lock-free concurrency and lower latency under load.

Async Server Architecture & Performance (Falcon Migration)

• Fiber-based concurrency: Migrated server stack to Falcon, leveraging Ruby fibers for high-throughput, non-blocking request handling ([#1139](#1139)).
• Lock-free cache modernization: Stripped thread mutexes across caching layers to align directly with the fiber reactor lifecycle ([#1141](#1141)).
• TLS hardening: Enhanced transport security defaults within the new server stack ([#1139](#1139)).

Core Upstream & HTTP Client

• HTTPX transport integration: Adopted upstream html2rss HTTPX strategy and modernized test mocking via the WebMock adapter ([#1138](#1138)).

Dependencies

• chore(deps): bump html2rss-configs to 2355ce1 by @dependabot in #1143
