Dev release v0.3.4.dev1

Add --hide-suggested-questions and --hide-build-context-hint CLI flags (

#47)

* Add --hide-suggested-questions and --hide-build-context-hint CLI flags

Introduces two new flags (following the --read-only-domain pattern) to
hide onboarding UI elements for demo deployments:
- --hide-suggested-questions: hides the suggested questions block on the empty chat screen
- --hide-build-context-hint: hides the 'Context isn't built yet' warning and removes the
  Build Context step from the setup wizard (renumbering the final step accordingly)

Both flags are enabled by default in the Snowflake demo app.

* tests: add CLI tests for --hide-suggested-questions and --hide-build-context-hint

Adds two tests that mock bootstrap_streamlit_app to assert the new flags
are parsed and forwarded correctly, and default to False when omitted.
