chore: upgrade from yarn 1.22 to yarn 4.16 (Berry)

- packageManager: yarn@4.16.0 + .yarn/releases/yarn-4.16.0.cjs (no corepack dependency for users)
- .yarnrc.yml: nodeLinker=node-modules (keep classic install), enableScripts=true
- yarn.lock regenerated in Berry format
- Husky pre-commit now uses "yarn install --mode=update-lockfile" (Berry-only equivalent of npm install --package-lock-only; refreshes lockfile in standalone mode without triggering postinstall or full install)
- CI: replace "--frozen-lockfile" with "--immutable" (Berry syntax) and add "corepack enable" step
- package.json: replace shell backticks with $(...) in test script (Yarn 4 shell does not expand backticks the same way Yarn 1 did)
- .gitignore: track only .yarn/releases, .yarn/plugins etc.; ignore the rest
