Subject: [PATCH] fix: increase stream watchdog timeout from 45s to 90s

Google upstream (Antigravity) thinking models can take >45s during
the thinking phase before producing any output, especially under
heavy load. The 45s watchdog was incorrectly treating these as zombie
connections and terminating the stream, causing clients to receive
overloaded_error and retry repeatedly.

Increased STREAM_ACTIVITY_TIMEOUT_MS from 45000ms to 90000ms to
accommodate longer thinking phases.
