Subject: [PATCH] fix: browsing folders in the terminal file browser breaks the
 prompt cache

With an Open Terminal connected, opening another folder in the terminal's file browser changed the tools sent to the model on the next message, because the current folder was written into the run_command tool's description. The provider's prompt cache then missed from the first byte and the whole chat was processed again. The tools now stay the same for the whole chat, and the current folder is reported in the result of each command instead.

Fixes #31589
