1. only trigger docker-dryrun arm64&riscv64 when dockerfile changes
2. de-duplicate "contents: read" permission for most workflows
3. merge various "lint-*" jobs into one job
4. add missing lint targets to the "lint" (all) target
Cache includes go, lint and unittests. Integration tests with their
standalone binaries are uncacheable with their current architecture.
Every Go job uses a new composite action (`.github/actions/go-cache`)
that restores and saves the Go module cache, a shared build cache, and
the golangci-lint cache. A `cache-seeder` workflow runs on `push: main`
to pre-populate those slots; PRs read them via GitHub's default-branch
fallback, so the common case is warm from the first commit.
Also dropped `-coverprofile` from `test-unit` (it silently disabled Go's
test result cache), and `-race` from `test-pgsql` and `test-mysql` (kept
on `test-unit` and `test-sqlite`).
