chore: resolve ts-node loader path and require deps for viv-debug

Fixes ERR_MODULE_NOT_FOUND for ts-node by:
- Pointing --loader to node_modules/ts-node/esm.mjs explicitly
- Running from repo root (pushd)
- Logging a clear error if node_modules is missing

Now viv-debug.cmd works without global ts-node.
