chore(build): Replace check.sh with granular Justfile recipes

Remove the monolithic check.sh script in favor of fine-grained Justfile
recipes (fmt, lint, test, check) and small shell wrappers.  This gives
faster feedback by short-circuiting on first failure and keeps CI output
silent on success.  Also drops unused JS/Node tooling (biome, prettier,
mdl) and consolidates pre-commit to a single hook.
