… 13.5h

Production incident 2026-08-15: cycle #25 completed at ~23:24 UTC on
08-14, and the runner produced no further output for ~13.5h while the
process stayed online (0% CPU). Root cause: the Delphi SDK (v2.1.0)
performs its HTTP calls with NO timeout of its own (verified by source
inspection — no AbortSignal anywhere in DelphiClient). A single hung
request to the Alchemy testnet RPC / Goldsky subgraph awaited forever,
and the runner loop only recovers from thrown errors, so the whole
competition agent silently froze.

Fixes, layered:
1. withTimeout() wraps every SDK call in the executor (health, list
   markets, quote buy/sell, buy/sell shares, redeem, liquidate, signer,
   balance, list positions) with a configurable deadline (sdkTimeoutMs,
   default 60s). A hang now becomes a retryable error — withRetry picks
   it up with the existing backoff, and cycle-level error handling then
   takes over.
2. Telegram sendMessage gets a 10s AbortSignal (it had no timeout and
   runs inside the cycle path).
3. Belt-and-braces cycle watchdog in start(): runCycle() itself is
   bounded at 50 minutes; if any unforeseen await still hangs, the
   hourly loop abandons the cycle (it keeps unwinding in the background
   under its own per-call timeouts) and moves on.

Also surfaced during diagnosis: the 1,000 TST starting bankroll landed
while the runner was hung, so no trade could execute; sizing math was
verified correct via the live executor path (budget 100 TST at price
0.4 → 250 shares).

Regression tests: withTimeout resolve/reject/propagate, hung balance /
listMarkets / healthCheck all bound by a 10ms injected deadline.
528 tests green, tsc clean.
