pass rc-disable flags and set prompt at session start

- Spawn shell with profile's rc_disable.flags (e.g. --norc --noprofile)
- After initial prompt wait, send prompt_set_command from profile
to force a known prompt pattern
- Use generous timeout for initial prompt detection

Fixes: bash sessions now start with clean environment and known
prompt instead of inheriting .venv PS1 and bashrc output.
