Fix race condition between heartbeat response and game updates

The heartbeat handler was reading game state and sending responses without holding the GamesManager lock. Since game updates ARE sent while holding this lock, there was a race condition where: 1. AI processing holds GamesManager lock 2. Updates start being sent to clients via the stream 3. Heartbeat request arrives, acquires EagleServiceImpl lock (different lock) 4. Heartbeat reads game count and sends response (can interleave with updates) 5. Client receives heartbeat before some in-flight updates 6. Client detects sync mismatch despite updates being in transit This particularly affected slower/remote connections (e.g., Windows clients) because the timing window for the race was longer. Fix: Wrap heartbeat handling in gamesManager.synchronized to ensure the response is sent only after any in-progress game updates have been queued. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>

adminandClaude Opus 4.5	68543fe68f	Fix race condition between heartbeat response and game updates The heartbeat handler was reading game state and sending responses without holding the GamesManager lock. Since game updates ARE sent while holding this lock, there was a race condition where: 1. AI processing holds GamesManager lock 2. Updates start being sent to clients via the stream 3. Heartbeat request arrives, acquires EagleServiceImpl lock (different lock) 4. Heartbeat reads game count and sends response (can interleave with updates) 5. Client receives heartbeat before some in-flight updates 6. Client detects sync mismatch despite updates being in transit This particularly affected slower/remote connections (e.g., Windows clients) because the timing window for the race was longer. Fix: Wrap heartbeat handling in gamesManager.synchronized to ensure the response is sent only after any in-progress game updates have been queued. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>	2025-12-26 19:28:13 -08:00
adminandClaude Opus 4.5	92a8e2e66f	Use environment dropdown URL for OAuth connections OAuthManager now gets its server URL from ConnectionHandler's environment dropdown instead of a hardcoded value: - Add SetServerUrl() to OAuthManager for deferred configuration - ConnectionHandler calls SetServerUrl() before OAuth operations - prod/qa/eagle0.net all use HTTPS as they're remote servers - AuthClient accepts full URL with scheme (no longer prepends https://) This ensures OAuth uses the same server as the main gRPC connection. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>	2025-12-26 19:14:01 -08:00
