Subject: [PATCH] fix: resolve ESLint circular structure crash and tsc OOM

- Replace FlatCompat bridge with native flat config imports from
  eslint-config-next (16.x exports flat configs directly)
- Remove unused @eslint/eslintrc devDependency
- Increase tsc heap to 4096MB for typecheck (55+ collections exceed 2GB)
- Exclude migrations, test artifacts from tsconfig type-checking
