The runtime gate (check_computer_use_requirements) and the hermes tools
platform_gate both enable linux alongside darwin/win32, but several
docstrings/comments still described Linux as "alpha, gated off until it
flips upstream" — contradicting the code that ships it. Bring the prose in
line with the gate that's actually live:
- tool.py / cua_backend.py module docstrings: Linux is enabled (X11 today,
Wayland via XWayland), not gated off.
- toolsets.py description and hermes tools display name: (macOS/Windows) ->
(macOS/Windows/Linux).
No behavior change — the gate already allowed all three platforms.
