Convert .golangci.yml to the v2 layout: linters-settings and issues.exclude-use-default were rejected by the v2 schema, so the lll, funlen, cyclop, and dupl settings were never applied. Disable exhaustruct_v5 (the newer major version of the already-disabled exhaustruct) and the deprecated gomodguard. Pin the golangci-lint image at v2.15.0 in the Makefile and Dockerfile.

# The checks behind `make check` are split across independent stages so that
|
|
# formatting and lint failures surface in seconds, before any compilation:
|
|
#
|
|
# lint - gofmt and golangci-lint (make fmt-check-go, make lint)
|
|
# docs - prettier check of all markdown (make fmt-check-md)
|
|
# builder - tests (make test) and the release build
|
|
#
|
|
# The builder stage declares explicit dependencies on lint and docs so
|
|
# BuildKit cannot finish the build unless every check passed.
