Nils 50302ed70a fix(tools): make browser SSRF check configurable via browser.allow_private_urls (#4198)
* fix(tools): skip SSRF check in local browser mode

The SSRF protection added in #3041 blocks all private/internal
addresses unconditionally in browser_navigate(). This prevents
legitimate local development use cases (localhost testing, LAN
device access) when using the local Chromium backend.

The SSRF check is only meaningful for cloud browsers (Browserbase,
BrowserUse) where the agent could reach internal resources on a
remote machine. In local mode, the user already has full terminal
and network access, so the check adds no security value.

This change makes the SSRF check conditional on _get_cloud_provider(),
keeping full protection in cloud mode while allowing private addresses
in local mode.

* fix(tools): make SSRF check configurable via browser.allow_private_urls

Replace unconditional SSRF check with a configurable setting.
Default (False) keeps existing security behavior. Setting to True
allows navigating to private/internal IPs for local dev and LAN use cases.
