Market-tick prices new NPC listings from the economy ledger (base x priceModifier, vendor modifier applied) instead of the old autoPrice +/-15% randomness, and scales restock quantity down under shortage. buyListing records real demand from completed purchases of NPC/vendor stock.

Add createBinLogger (src/scripts/lib/binFileLogger.ts): every log call
is appended synchronously to logs/<bin-key>/<YYYY-MM-DD>.log (UTC) in
addition to the console logger — sync writes because bin scripts
process.exit() immediately. Bin bodies are wrapped in try/catch so a
fatal error is logged to file and exits code 1. Override the directory
with BIN_LOG_DIR. logs/ is gitignored.
game-tick, market-tick, and processShipmentTick adopt the logger;
generate-mission follows with its clone fix; mission-tick lands with
its feature. Document BIN_LOG_DIR in .env.example and the logging in
AGENTS.md / README.
Tarkov-style flea market where users list locker items at a fixed price

into the buyer's locker.
