- #62720: \[Bug\]: Local sessions can execute tools on a previous remote terminal backend

These issues and PRs address a bug where locally cached environments or terminal sessions retain a stale backend type, potentially causing tools to execute against an unintended previous remote backend. The work involves validating and evicting cached state when the backend type no longer matches current config.
