pr/edgar: Cody gate — cache company_tickers.json (1h TTL). The ~1MB static file (SEC publishes daily) was fetched + deserialized + O(n)-scanned on EVERY searchCompanies call; now fetched at most once per process-hour via getTickersData(). Removed dead-code cleanup exposed this as the real latency/SEC-fair-access cost. Verified: 3 searches in-window → 1 fetch; after TTL → refetch
