Replace the hand-migrated v2 config with the exact output of
golangci-lint migrate under v2.12.2, applied and verified on
dnswatcher (sha256 8804ff50ebba0e8b4129a03600137040421e43aef9b4054a626abfd13767b28b):
- disable deprecated gomodguard (gomodguard_v2 stays enabled via
default: all; identical behavior, resolves the deprecation warning)
- add linters.exclusions and formatters.exclusions (generated: lax,
default path excludes) replicating v1 defaults
- add explicit formatters block (gofmt, gofumpt, goimports); gci is
intentionally not enabled because its two-group import ordering
conflicts with the org's stdlib/third-party/local script/fmt style
- drop the explanatory header comment so the file is byte-identical
with the verified copy consuming repos fetch
Update the TODO.md Completed Steps entry to match.
Move linter settings from the broken v1-style top-level linters-settings
key to linters.settings so golangci-lint >= v2 actually applies the
thresholds, and drop issues.exclude-use-default, which no longer exists
in the v2 schema. Add a comment documenting the v2 layout requirement.
Record the change in TODO.md Completed Steps.
