catarrh a76e0154b6 v3.22.2: the runner's TERMINAL RESPONSE inherits the terminal's own objects
Two reported gaps:

- a scripted PROVIDE LOCAL INFORMATION expectation answered with an empty
  TR - the PLI dictionary (and the host clock for the date/time qualifier)
  was silently inert during runs while the poll path used it all along, so
  an applet waiting for its data stalled behind a passing expectation.  A
  POLL INTERVAL expectation likewise never echoed the Duration (6.8.4).
  testscript.build_tr() gained `answer_tlvs` (inserted after the Result per
  the 6.8.0 order, before text/item/raw) and the shared
  _test_terminal_response() wires the expect step, the proactive-drain
  action and the run cleanup to it; the script's `raw` overrides, and a
  non-success result gets no data object.
- a GP INSTALL/LOAD/DELETE step always failed the default exact-9000 check
  although the envelope SW 91XX is the successful answer (the re-announced
  SET UP MENU; XX is the pending command's length, never pinnable).
  Documented rather than loosening the default: a new "Driving a RAM install
  from a script" subsection in docs/test-scripts.md (the 9??? mask + por
  any, the per-step pending rule - a proactive-drain/expect after every
  91XX step), a sentence at the sw-default bullet, and an scp80
  default-pinning test.

Docs: api.md's respond clause, help EN/RU's TR Config note.
Tests: 839 frontend + 812 Python; sw cache simple-v406.
