feat(scripts): add pre-commit library-decisions check + tests

Adds scripts/library-decisions/check.mjs that walks staged package.json
diffs, derives tier from path, and fails the commit when a new runtime
dependency in a feature- or core-tier package has no sibling approved
trace staged in docs/library-decisions/.

App-tier additions and devDependency / peerDependency additions are
silently allowed. Wired into .husky/pre-commit as step 4.

check.test.mjs covers all 7 Done-when cases using temp git repo
fixtures (node:test + node:assert, same pattern as schema.test.mjs).
