[BUG] Cowork: request_cowork_directory rejects the home directory itself with no path to grant it or a subtree

This concerns Cowork mode in the Claude desktop app.

request_cowork_directory fails immediately with:

Cannot mount the home directory itself. Choose a subdirectory.

There's no documented reason given in the tool's error or description, and no way to grant the home directory (or its full subtree in one action) at all — each subfolder has to be connected individually via the picker. This makes any request like "look through my whole home folder" or "clean up my computer" require either many separate connect actions, or the user manually navigating into a specific subfolder each time.

Related but distinct from prior filed issues about folders outside the home directory being rejected (e.g. #29583, #41312) — this is the opposite case, the home directory itself is the one folder that can never be selected, on macOS.

Requesting either:

1. A documented rationale for why the home directory itself is excluded, or
2. A way to grant a directory and its full subtree in one picker action, rather than requiring the home directory specifically to be excluded with no equivalent broad-grant alternative.
