feat(studio): force advanced reflection during browser-test sessions (v0.7.2)

When at least one browser_test session is connected, every chat
message in Studio now auto-enables advanced reflection regardless of
the user toggle. The intent: during AI-driven UI testing, having a
second model produce a preliminary [RAPPORT PRÉALABLE] materially
improves which clicks the active model decides to perform and the
quality of the final ✓/✗ report.

- handlers_chat: derive wantReflection from body.AdvancedReflection
  OR (browserTestStore has any active session). The user toggle still
  works for normal conversations; tests just override it.
- Silent fallback when no inactive provider is configured (no error,
  no behaviour change for single-provider setups).
- Tests.jsx: add a hint explaining the auto-on behaviour so the user
  understands why the Studio toggle appears bypassed.
- Version 0.7.1 → 0.7.2 + CHANGELOG entry.
