Add .golangci.yml (v2): the standard linters plus bodyclose, errorlint, noctx, misspell, rowserrcheck, sqlclosecheck, unconvert, usestdlibvars, with gofumpt + goimports formatters. Enable the std-error-handling exclusion preset for idiomatic Close/Remove/Setenv ignores; scope-exclude SA1019 (parser.ParseDir in tools/openapigen) and ST1005 (intentional capitalized user-facing error copy that tests assert verbatim). No inline nolint directives were introduced.
Resolve all 217 findings behavior-preserving: gofumpt/goimports formatting, explicit blank assignment on intentionally ignored errors, errors.Is/errors.As and %w wrapping, context-aware stdlib calls (CommandContext/QueryContext/NewRequestWithContext/Dialer), staticcheck simplifications, removed redundant conversions, http.StatusOK and http.MethodGet, inlined the go:fix intPtr helper, and deferred sql rows Close. Add a golangci CI job mirroring the existing Go jobs.
applyClientFieldByEmail patched only the first inbound that the
client_traffics row pointed at. For a multi-inbound client the sibling
inbounds kept the old expiryTime/totalGB/limitIp in their settings JSON,
and the next SyncInbound over a stale sibling reverted the edit in the
normalized records — the Telegram bot's expiry change appeared to apply
and then sprang back. Patch the field on every inbound linked to the
email, falling back to the legacy single-inbound lookup for clients that
were never normalized.
