check / check (push) Failing after 2s
Pin the remaining developer tool installs (closes #68)
gofumpt and protoc-gen-go are tools of a separate Go module in bin/tools,
so `go tool` builds them from source checked against bin/tools/go.sum and
mfer's own module gains no dependencies. script/bootstrap downloads that
module, and unpacks protoc 33.4 into bin/protoc from its release archive
after checking the sha256 it holds for the platform. script/generate runs
that protoc with the pinned plugin, so mfer/mf.go and its go:generate line
go. script/prettier runs only the node_modules prettier, fails when it
differs from the package.json pin, finds the node bootstrap installed
through nvm by the version in .nvmrc, and runs prettier once. Comment and
package.json fixes.

# script/prettier: run prettier over this repo's canonical file set.
#
# 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.

# erroring out is exactly what we want rather than a vacuous pass.
