browser_vault reached pages only through the task's CDP supervisor. Camofox (now a plugin) has no CDP endpoint, so every fill on a Camofox tab ended with "Could not determine the current page origin": the username from browser_vault list worked, the password never filled. ctx.register_browser_page_backend lets a plugin browser carry the vault's origin read, form inspection and fill script to its own page. Core keeps the secret contract: the exact-origin pre-check and in-page re-check, the Bot Desktop takeover check, an in-page try/catch around the secret script, and fixed failure text on that path. Registration follows the login-backend provenance rule (bundled, or catalog verified/official at its pin) and is refused under plugins.isolation: host. Consolidates the core half of #127179 and #135204 (the Camofox halves already shipped in the official plugin); the in-page wrapper follows #114414.
