Note

Low Risk
Low risk: adds a new CI workflow only, with no production code changes; main impact is potential new PR gating if TypeScript checks fail.

Overview
Adds a new GitHub Actions workflow (.github/workflows/ci.yml) that runs on pull_request to main and merge_group events.

The job checks out the repo, sets up Bun, installs dependencies with a frozen lockfile, and runs tsc --noEmit to enforce TypeScript type checking in CI.

lgtm — small CI workflow, does what it says. type check only for now (no lint/build), but fine as a starting point for SOC 2 CHG-1.
