ReplicantX Browser Mode (Playwright)

[gusfraser]

Add a new interaction_mode: browser to Level 2 (level: agent) scenarios.

In browser mode, a Replicant:

1. Authenticates programmatically (Supabase admin magic-link → verify → app /auth/refresh to set httpOnly cookies)
2. Opens the app URL in Playwright (headless by default; headed optional)
3. Iterates up to max_turns:

• Observes page state (DOM text + interactive controls)
• Chooses an action (send chat, click card/button, fill field, wait, etc.)
• Executes action
• Evaluates progress (DOM and/or screenshot)

4. Produces artifacts (trace, screenshots) + enriched report

Key principle: keep the existing Replicant configuration (facts/goal/system_prompt/goal_evaluation/false positives) and introduce only additive fields for browser automation.
