This PR:

• adds parent to both Android CAPTCHA action models, because Android drops broker fields that the Kotlin models do not declare.
• passes the matched-row scope to content-scope-scripts for getCaptchaInfo and solveCaptcha. Android only forwards the field, while content-scope-scripts handles the matching and CAPTCHA logic.

---

Note

Low Risk
Small PIR model/serialization change so an existing broker field is no longer stripped. No new CAPTCHA or matching logic on Android.

Overview
Stops Android from dropping broker parent on CAPTCHA actions so content-scope-scripts can scope getCaptchaInfo and solveCaptcha to the matched profile row.

Adds optional parent on GetCaptchaInfo and SolveCaptcha (same ParentElement used by form selectors). The native layer only deserializes and forwards the field; matching and CAPTCHA handling stay in C-S-S. A processor test checks profileMatch is pushed through for both action types.
