Migration is required. TypeScript 7 removed the JavaScript Compiler API (used by vite-plugin-dts for .d.ts generation), causing the build to fail with:

The installed "typescript" package does not provide the JavaScript Compiler API (this happens with TypeScript 7+)

The fix (per the TypeScript 7 announcement) is to install the @typescript/typescript6 companion package alongside TypeScript 7 — it provides the legacy JS API as a fallback for tooling.

Added in commit fix: add @typescript/typescript6 companion package for TypeScript 7 build tooling compatibility. Build and all 19 tests pass.

Branch conflict resolved. The conflict was between our @typescript/typescript6 addition and the @vitest/coverage-v8 bump (4.1.8 → 4.1.10) on main — both changes are now present. Build and all 19 tests pass.
