Fix misleading npx hints in live-mode poll/wrap scripts (#275)

* Replace npx hints in live scripts with bundled-script paths

The live-mode poll/wrap scripts are invoked by the agent via
`node {{scripts_path}}/live-*.mjs`, never through the `npx impeccable`
CLI. Their help text and runtime error hints still pointed at
`npx impeccable poll|live|wrap`, which is misleading and, for the
error paths, not directly runnable.

- Docstrings/comments (never executed): switch to the
  `node <scripts_path>/...` convention already used by live-server.mjs.
- Runtime-printed error/usage strings: resolve the script's own dir via
  import.meta.url and print a real, copy-pasteable absolute path instead
  of a placeholder.

Verified by triggering the error paths from the synced bundle and by
running the live-mode E2E (vite8-react-modal) through the full cycle.

* Quote script paths in runtime hints to handle spaces

Paths containing spaces (e.g. /Users/john doe/...) would otherwise
produce a non-runnable command. Addresses Greptile review feedback.
