🛡️ Sentinel: [MEDIUM] Add timeouts to external fetch requests

[felirami]

User description

🚨 Severity: MEDIUM
💡 Vulnerability: External fetch requests without explicit timeouts can hang indefinitely if the remote server fails to respond, leading to resource exhaustion, memory leaks, and potential Denial of Service (DoS) conditions.
🎯 Impact: Prevents server resource exhaustion or blocked executions resulting from unresponsive third-party APIs (e.g. GitHub API, DexScreener API, external Farcaster Node endpoints).
🔧 Fix: Added signal: AbortSignal.timeout(...) to all native fetch calls. Added constants for timeout durations where appropriate (MARKET_FETCH_TIMEOUT_MS = 10_000, and reusing existing NODE_PROBE_TIMEOUT_MS or 10000).
✅ Verification: Verified by successfully running npm run lint, npm run typecheck, and npm run build locally without introducing regressions. The code changes are purely defensive.

CodeAnt-AI Description

Add timeouts to external requests so slow services do not hang the app

What Changed

• External requests now fail after a fixed time instead of waiting indefinitely
• Network checks, market data fetches, and GitHub sync requests are covered
• This reduces the chance of stalled jobs and blocked server work when third-party services are slow or unresponsive

Impact

✅ Fewer hanging API requests
✅ Lower risk of blocked background syncs
✅ Fewer resource exhaustion incidents
