fix(vscode-ide-companion/session): improve timeout configuration for different methods

Extend timeout duration to 2 minutes for both session_prompt and initialize methods
to prevent timeouts during longer operations. Default timeout remains at 60 seconds
for other methods.

This change improves reliability of session management by providing adequate
time for initialization and prompt operations to complete.
