fix(tools): wrap browser provider network calls with error handling

Browse source 
Wrap requests.post() in create_session() for browser_use, browserbase,
and firecrawl providers with requests.RequestException handling.
Connection timeouts and DNS resolution failures now surface as clean
RuntimeError messages instead of raw requests exception tracebacks.

Browser Use managed-gateway mode preserves raw exception propagation
so the existing idempotency-key retry semantics keep working.

Closes #2746
