Python: Move ag_ui_workflow_handoff demo from demos/ to 05-end-to-end/ (#4900)

* Move ag_ui_workflow_handoff demo to 05-end-to-end (#4895)

Move the AG-UI workflow handoff demo from python/samples/demos/ to
python/samples/05-end-to-end/ to follow the current folder structure
convention. Update README paths accordingly.

* Fix review feedback: remove build artifacts, fix README paths (#4895)

- Add .gitignore to frontend/ to exclude *.tsbuildinfo, vite.config.js,
  and vite.config.d.ts build artifacts from version control
- Remove the 4 tracked build artifact files from the tree
- Fix step 2 cd path in README to be relative after 'cd python'

* Clarify working directory context in README Step 2 (#4895)

Step 2 uses a python/-relative path (samples/...) which assumes the
user is still in the python/ directory from Step 1. Add a brief note
making this explicit.
