Subject: [PATCH] chore(ci): add typecheck scripts for local TypeScript
 verification

Adds a yarn typecheck script in the repository root and per-package typecheck
scripts that run tsc --noEmit in each TypeScript workspace (web, backend,
db, schemas, shared). Mirrors the existing test/lint conventions: root uses
yarn workspaces foreach --all --topological, per-package scripts execute
the same TypeScript compiler invocation in isolation.

A new .github/workflows/typecheck.yml CI workflow is intentionally NOT added
in this commit because running tsc --noEmit on the current main surfaces
~175 latent type errors in the web package (test fixtures referencing
schema-drift columns added to migrations 20260702000000 and 20260702000001
but not yet declared in schema.prisma). A follow-up PR will fix the
schema-drift, update test fixtures, then add the CI workflow.

Mirrors CONTRIBUTING.md 'Developer tooling' / 'Bug fixes' guidance: pure
additive tooling, no source code changes, no new dependencies.
