AST-driven pass over every subprocess.run/Popen/check_output/check_call/call
with text=True (or universal_newlines=True) and no explicit encoding=:
append encoding='utf-8', errors='replace' at the kwarg site. 136 call
sites across 28 files (cli.py, hermes_cli/main.py, tools_config.py,
environments, computer_use, gateway, scripts, skills helpers, agent/*).
Together with the salvaged #55339/#60741 commits this closes out issue
#53428's bug class; the salvaged #60751 linter rule in
check-windows-footguns.py now enforces it repo-wide (verified: 807 files
scanned, zero findings).
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.
