docs: drop the pr3840 no-boards handoff, both halves are doneclaude/prompt-audit

The doc half landed in this branch. The test half it asked for already
exists: NoBoardsExitRespectsFreshness and TheNoBoardsCallSiteIsWired in
test/hil/test/test_hil_report.py (375e20090) cover the fresh and
--accumulate no-boards exits through mark_report_no_boards.

-# `SKILL.md` no-boards bullet: the regression test is still missing
-
-**Origin:** split out of PR #3840, surfaced by its second review round. Delete this file
-when its own PR lands.
-
-The documentation half landed in PR #3881. `.claude/skills/hil/SKILL.md`'s
-`**HIL run selected no boards.**` bullet (under "Reporting") now describes both cases: a
-fresh run renders no table, and an `--accumulate` run keeps the previous attempt's rows
-under the notice, which are not this run's and must not be reported as such. That matches
-the code, which deliberately preserves accumulated rows on a no-boards exit because wiping
-them destroyed real results.
-
-**What remains:** a test asserting that the fresh no-boards case renders no matrix while
-the `--accumulate` case keeps the prior rows under the notice, so the two halves cannot
-drift again. The behaviour lives in `test/hil/helper/hil_report.py`'s no-boards exit
-(`accumulate_report` with `fresh`); `test/hil/test/test_hil_report.py` is the suite.
-
-## Why it was split out
-
-PR #3840 fixed the findings that changed a verdict. This is a documentation drift: the
-behaviour is correct and the doc describing it is not, so it is better reviewed on its own
-than appended to a branch already carrying a module consolidation.
