Jeff Watts f708a85d2e test(tui_gateway): make the tui gateway suite order-independent
Cross-file leaks made tests/tui_gateway + tests/test_tui_gateway_server.py
fail when run in one process (issue #57068):

- conftest: _hermetic_environment now re-pins hermes_state.DEFAULT_DB_PATH
  to the fake home so no test ever touches the developer's real state.db
- conftest: new autouse _reset_tui_gateway_server_state snapshots/restores
  _methods, cfg cache, db handle and _real_stdout, and tears down leftover
  sessions via the production _close_session_by_id(..., end_reason=
  "test_cleanup") boundary
- per-file fixtures scope patch.dict(sys.modules) to the import only
- drop reload()-based teardowns that duplicated atexit hooks

Conflict resolution vs main: kept main's mod._live_transports.clear() in
the test_protocol.py server fixture alongside the snapshot/restore logic.

Combined run now 792 passed / 0 failed.

Salvaged from PR #57066 by @lEWFkRAD. Fixes #57068.

"""Regression tests for the conftest live-system guard's argv handling.
The guard must treat only argv[0] of a list/tuple command as the executable
(arguments are data: a file named ``skill`` is not the ``skill`` binary),
while still scanning every token of wrapper invocations like ``bash -c``.
All blocked-case commands use patterns that match no real process, so a
guard regression cannot kill anything.
