check / check (push) Failing after 2s
Pin the remaining developer tool installs (closes #68)
gofumpt was pinned only by its version tag. It is now a tool of a
separate module in tools/, so `go tool` builds it from source checked
against the hashes in tools/go.sum, and mfer's own module gains no
dependencies. script/prettier no longer falls back to a prettier on
PATH, and fails when node_modules holds a different version than
package.json pins. The bootstrap comment now says what --frozen-lockfile
really does, package.json drops its made-up version, and the golang
image comment names its exact version.

# Takes exactly one mode argument, --write or --check, and applies the
# same patterns in both modes. script/fmt and script/fmt-check both go
# through here, so the set of files that get formatted and the set that
# get verified cannot drift apart.
#
# Failures are never swallowed: a missing prettier is an error, not a
# silent skip. A formatter that quietly does nothing is worse than one
# that fails loudly.

# Markdown and JSON, repo-wide rather than root-only, so files in

# live in .prettierignore; REPO_POLICIES.md is excluded there because
# it is a verbatim copy of an upstream document.
#
# --no-error-on-unmatched-pattern is deliberately NOT used: both
# patterns always match at least one tracked file (README.md,
# package.json), so an empty match means the glob broke, and prettier
# erroring out is exactly what we want rather than a vacuous pass.
