Script the gate rollout instead of hand-copying it into sixteen repos
The gate is three files per repo -- a delegate, a pre-commit hook entry and a
CI workflow -- and Phase 3 needs them in sixteen more repos. Hand-replication
is precisely how the 250-line cap ended up shipping under four different hook
ids, two of which were independent reimplementations rather than delegates, so
the copy is now a script and the templates have exactly one home.

  scripts/install_dependency_freshness_gate.sh <repo> [--check] [--fvm]

Idempotent, and it rewrites a copy that has drifted from the template rather
than leaving it. `--check` reports without writing. `--fvm` pins the Flutter
SDK, and only in a repo that actually holds a pubspec.yaml -- an .fvmrc in a
Python repo declares a toolchain nothing there builds with. An unresolvable
SDK version leaves the pin alone and exits 1: guessing would pin every repo to
a number nobody chose.

The pre-commit block is APPENDED rather than parsed and re-emitted. Every one
of these configs carries comments explaining why its hooks exist, and a YAML
round-trip through the standard library drops all of them.

306 tests, 100% branch coverage on every production module.

# Thin delegate to the shared gate in ~/utils, which owns the registry

# repo's -- so this script only locates the shared checker and forwards its
# arguments.
