Subject: [PATCH 1/2] fix(pre-commit): type-check with tsc -b so build errors
 are caught

The root frontend/tsconfig.json is solution-style (files: [], only
project references), so the pre-commit hook's plain tsc --noEmit
resolved to it and type-checked zero files under src/. A build-breaking
type error could pass the gate locally and in CI, only surfacing in the
real build (tsc -b && vite build).

Switch the hook to tsc -b --noEmit (project-reference build mode, no
emit), matching what the build actually checks.

+Corrected the pre-commit TypeScript check to use project-reference build mode (`tsc -b`), so build-breaking type errors are caught before they reach CI.
