- Fix .golangci.yml for v2 format (linters-settings -> linters.settings) - All production code now passes golangci-lint with zero issues - Line length 88, funlen 80/50, cyclop 15, dupl 100 - Extract shared helpers in db (scanChannels, scanInt64s, scanMessages) - Split runMigrations into applyMigration/execMigration - Fix fanOut return signature (remove unused int64) - Add fanOutSilent helper to avoid dogsled - Rewrite CLI code for lint compliance (nlreturn, wsl_v5, noctx, etc) - Rename CLI api package to chatapi to avoid revive var-naming - Fix all noinlineerr, mnd, perfsprint, funcorder issues - Fix db tests: extract helpers, add t.Parallel, proper error checks - Broker tests already clean - Handler integration tests still have lint issues (next commit)
