fix: re-apply download behavior on recording context (#1019)

* fix: re-apply download behavior on recording context

record start creates a new browser context via Target.createBrowserContext.
Browser.setDownloadBehavior called at launch only applies to the default
context, so downloads in the recording context are silently dropped.

Fix:
1. Store download_path on BrowserManager (from LaunchOptions)
2. After creating the recording context, call Browser.setDownloadBehavior
   with the new browserContextId

This ensures downloads work during recording.

Fixes #1018

* fix: add download_path to third BrowserManager constructor (auto_connect_cdp)
