teknium1 d09dacf66a test: purge low-value tests, lane py10 (412 removed)
Change-detectors, tautologies, source-reading tests, redundant duplicates,
mock-echo tests and dead/unrunnable tests. Per-test rationale in the lane
ledger (category + reason for every removal).

"""Regression tests for classic-CLI mid-run /bg and /btw dispatch.
Background
----------
``/bg`` (formerly ``/background``) exists to start independent work while
the current turn keeps running. Typed while the agent was busy it went into
``self._pending_input`` like ordinary input, and ``process_loop`` is blocked
inside ``self.chat()`` for the whole run, so the background task only started
once the foreground turn had finished. That is the one moment it was not
needed (#75221).
``/steer`` had the identical problem and was fixed by dispatching inline on
the UI thread; the command's own ``CommandDef`` already declares
``busy_policy="dispatch"``, which the gateway honours and the classic CLI
never consulted.
These tests exercise the detector without starting a prompt_toolkit app,
mirroring tests/hermes_cli/test_cli_steer_busy_path.py.
