chore(deps): upgrade TypeScript to v7 and migrate tsconfig - #345
Merged
Conversation
TypeScript 7 removes the 'baseUrl' compiler option and requires 'paths' entries to be relative (leading './'). Update tsconfig.json accordingly. The '@/alias is also resolved by Vite's resolve.alias in vite.config.ts, so only tsc --noEmit was affected. Verified: tsc --noEmit clean, e2e typecheck clean, 339/339 vitest tests passing.
