Subject: [PATCH] Fix Anchor Browser adapter using an outdated connection
 method

Connected via a bare wss://connect.anchorbrowser.io?apiKey=... URL, which isn't how
Anchor Browser's API works today. Anchor Browser's blog-published connection numbers
(5,582ms avg, ~8x every other provider) were very likely measuring this broken/outdated
path rather than Anchor's real performance.

Fixed to match Anchor Browser's current API: POST /v1/sessions to create a session,
use the returned cdp_url to connect, DELETE /v1/sessions/:id to tear down. Verified with
a live run against all 4 providers -- Anchor Browser's connection time now lands in the
same range as the other three (243-689ms depending on run/region), not an 8x outlier.
