fix: remove sandbox language from tool descriptions

Browse source 
The terminal and execute_code tool schemas unconditionally mentioned
'cloud sandboxes' in their descriptions sent to the model. This caused
agents running on local backends to believe they were in a sandboxed
environment, refusing networking tasks and other operations. Worse,
agents sometimes saved this false belief to persistent memory, making
it persist across sessions.

Reported by multiple users (XLion, 林泽).
