Add hermes_cli/windows_ssh_runtime.py: a native Windows trust boundary
invoked over SSH to manage the Desktop SSH backend lifecycle — ACL-locked
one-shot token file (owner+SYSTEM only, SE_DACL_PROTECTED, read-once via
DELETE_ON_CLOSE), ownership lock, and detached serve spawn with
CREATE_BREAKAWAY_FROM_JOB so the backend survives the SSH session's Job
Object teardown. Process ownership is proven by exact pid + creation-time +
argv + owner-nonce; state is tri-state (owned / stale / indeterminate) so a
live-but-unreadable process is never mistaken for stale.
Route _read_ssh_session_token_file to the Windows reader on win32, and move
the POSIX token root from a hardcoded ~/.hermes to get_hermes_home() so both
platforms honor the active profile.
Accept descriptor-safe one-shot token files and exact owner nonces, expose an authenticated ownership proof endpoint, and preserve the process-local contract across parser and server startup paths.
