ScottW514 520d62ac05 forgetest tests: the confirmed trims of the tool's own unit tests
The cases that tested a mock, a timer, a wording or a table, or that
replayed a judgment a host test already holds, leave forgetest/tests.
What catches a false PASS, keeps the bench safe, or guards the gate
stays.

- test_baseline: the fake sysfs tree is a mixin with no test_ methods,
  so ExtensionFreeTests and BaselineModeTests no longer re-run
  BaselineTests' 25 cases (133 runs, now 45). CoolPublishTests, the
  lamp-fade cases and TransientNotLeftoverTests go; PositionDeadbandTests
  keeps a reading past the band and an unreadable reading, both never
  excused. Both latch-relock cases stay.
- test_fixture: MdnsTests, the three timing cases, the probe's log
  wording, and nine prompt-routing variants go. A live test never runs
  unattended, the arm-press opt-in, the short-press edge, the presence
  press handing over the arm press, and the arm notice dropping at the
  press stay (35 cases, now 21).
- test_cloud_suite: three false-PASS guards stay: the latch open at a
  dark print's button, a lid stop that is not edge-driven, the kernel
  refusing the resume. The guards for the latch unlocking in the hold
  and a paused print resuming left with their catalog tests in 6a434bb.
  The rest go, with the harness pieces and the hunt-lid fixture only
  they read (41 cases, now 3).
- test_cooling_suite: GateOffTests, CriticalTierTests, FanGateTests and
  FansQuietTests go with their harness; the flow verdict's log reads
  stay: only the text after the offset, never an older verdict before it
  (the flow-under-load false-PASS guard), a rotated log read whole.
- test_queue: RunClockTests and three ordering cases go, and refusals
  are judged by a reason given, not its words; both live
  acknowledgment cases stay.
- test_takeover_position: the six cases that judge the head and move
  nothing stay.
- test_camera_home_return: the five cases where the head must not move
  stay, and so do the three that check the hand-back jog's direction and
  distance (homed, unhomed with the counters not counted twice, after
  cloud mode): a wrong sign or a double count drives the head into the
  gantry stops (15 cases, now 8).
- test_server: the keep-alive and ETag cases, the takeover and scope
  half of the bench case, and the page's self-contained asserts
  (test_page.py's) go.
- test_operator: the wording cases, the fixture case (test_fixture.py's)
  and JournalTests go.
- test_mode: the supervisor timeout table goes.
- test_takeover_client: the listener, the offline service back, the
  online client without the hunt, and GRBL under no marker stay.
- test_responsiveness: PageTests and ImplementationCostTests go; the
  log cache keeps appends, a partial line, a replaced file and a fresh
  list, and the fingerprint cache a changed manifest and one with no
  content hash.
- test_bench_registry: GfbenchTests and two description and argument
  pins go.
- test_installer: the log-format and TLS-wording cases and
  InstallerShapeTests go; the die case checks the reason is in the log,
  not its format.
- test_image: KernelIdentTests and the registration pin go.

Each file's __main__ guard now ends the file, and the docstrings say what
each still proves.

Proof: each of the fifteen files passes under Linux as forgetest-ci
discovers it, and pyflakes reports nothing new in them.

Acceptance: none; test-only.

"""The bench actuator as the tool sees it.
The fixture is a box on the network that opens the lid loop, pulls the
interlock loop and presses the button on request. What has to hold: the
tool speaks its API under the key, falls back to the operator when it
cannot act, moves an operator test it can perform alone into the
unattended queue (never a live one, never one that needs a person for
anything else), refuses a prompt during such a run rather than hanging on
it, releases what the box still holds after every run, and presses the
arm button only where the bench opted in.
