Update golangci-lint to v2.12.2 with canonical config
- Replace .golangci.yml with the canonical v2-schema config: linter
  settings move under linters.settings (the previous top-level
  linters-settings block was ignored by golangci-lint v2, so the
  configured thresholds were not applied) and the obsolete
  issues.exclude-use-default key is dropped.
- Bump golangci-lint from the v2.10.1-era commit pin to @v2.12.2 in
  Dockerfile and script/bootstrap; refresh pin date comments.
- Wrap long lines in attrsum.go to satisfy the now-effective lll
  limit of 88 columns (15 findings); move one nolint:gosec directive
  to its own line.
- Record the change in TODO.md Completed Steps.

# script/bootstrap: install all dependencies needed to build and develop
# this repo. Idempotent: every install is guarded by a check so already
# installed tools are skipped. Base tooling comes from nix, apt, brew,
# or apk (detected in that order); assumes nothing is present.
# golangci-lint and goimports are installed via `go install` at the same
# pinned refs the Dockerfile uses (never "latest").
