feat(typecheck): add Golar support

[OskarLebuda]

🔗 Linked issue

Related #1316

📚 Description

nuxi typecheck can now use Golar as an alternative to vue-tsc. If Golar is installed in the project (or a golar.config.* file exists), it gets picked up automatically - otherwise the behavior stays the same as before. When no type checker is found, the interactive prompt now lets you choose which one to install, and a minimal golar.config is generated if needed.

You can also force a specific checker with --checker=vue-tsc|golar. This is helpful for noTTY.

DEMO:
vue-tsc:

vue-tsc.mov

golar

golar.mov

📝 Walkthrough

Walkthrough

This PR updates the nuxi typecheck command to support vue-tsc or Golar, including checker selection, resolution, installation prompts, Golar config creation, and checker-specific argument handling. It also changes README help text for the command and updates withNodePath() to split NODE_PATH with Node’s platform delimiter.

Inline comments:
In `@packages/nuxi/src/commands/typecheck.ts`:
- Around line 91-95: The checker validation in typecheck.ts is too loose because
`checkerArg in TYPE_CHECKERS` accepts inherited properties like toString and
constructor. Update the guard in the `checkerArg` validation block to check only
the explicit keys of `TYPE_CHECKERS` (using its own-property/key set) before the
`TypeChecker` cast, so invalid CLI values are rejected consistently with the
existing error path.
- Around line 200-205: The NODE_PATH parsing in the typecheck command and shared
path utilities is hardcoded to split on “:”, which breaks on Windows and
drive-letter paths. Update the NODE_PATH iteration in the typecheck logic and
the corresponding split in the paths utility to use path.delimiter instead,
keeping the existing resolve/existsSync flow unchanged.
