Add a max-session cap (default 10k) and optional idle TTL with lazy eviction. New sessions past the cap are rejected with 503, preventing memory exhaustion via repeated initialize requests. Assisted-By: Claude Opus 4.7 <noreply@anthropic.com> Signed-off-by: Sergey Vilgelm <sergey@vilgelm.com>

📌 Summary
The in-memory session store was unbounded with no idle expiry, so anyone could fill it via repeated
initializerequests and exhaust memory. The store now enforces a maximum session count (default 10,000) and an optional idle TTL, and the server rejects new sessions past the cap with503 Service Unavailable.🔍 Related Issues
