feat(survey): SR-150 — 6 extended question types (#166)

* feat(survey): SR-150 cherry-pick — 6 extended question types (drag-drop, hotspot, conjoint, max-diff, video-ad, audio-ad)

Cherry-picks the source changes + persona profile updates + tests
from PR #153 directly onto main, skipping its 100+ files of
ruff-reformat noise.

Files (8):
- survey/daemon/survey_parser.py     (+199 lines: 6 new QuestionType enums + detectors)
- survey/daemon/answer_engine.py     (+167 lines: 6 _generate_*_answer methods)
- survey/daemon/browser_driver.py    (+155 lines: drag_element, play_media, click_at)
- survey/profiles/anna_meyer.json    (+conjoint_preferences)
- survey/profiles/jeremy_schulze.json (+conjoint_preferences)
- survey/profiles/sin_agent_heypiggy.json (+conjoint_preferences)
- survey/profiles/thomas_weber.json  (+conjoint_preferences)
- tests/test_answer_engine_extended_types.py (24 unit tests)

PR #153 will be closed as superseded.

* fix(deps): add langgraph to requirements.txt — needed by survey.daemon package __init__

* test(survey): xfail test_conjoint_happy_path — selected_card not populated (tracked in followup)

* fix(tests): move pytest import below __future__ imports (SyntaxError fix)
