docs: remove the #238 lane --- the promised final pre-merge commit

The lane recorded this PR while it was under review, because an open PR
without a lane is the #171 defect: it drifted 153 commits while
invisible in the ledger. Review is done, so the lane goes.

**It had to go in a commit rather than "at merge".** GitHub merges the
tree as it stands, so leaving it would have landed the words *PR #238
OPEN* on `main` --- a lane advertising an open PR that closed in the
same commit, which is the exact staleness class this absorption exists
to clear.

Rule 4 takes it **outright** rather than rewriting it: a lane is
rewritten when its ARC survives its PR, and this one describes a docs
pass with nothing left behind it. Every reference to #238 and to the
`docs-absorb-237` branch lived inside the lane, so the deletion is
self-contained and leaves no dangling pointer.

What the lane recorded that outlives it is already elsewhere: the
recovery rehearsal and its floor checks are in "Repository authority",
and the GUI arc's state is in the Stage 1 lane and the handoff anchor.

## Docs absorption of #236 and #237 — PR #238 OPEN, docs only
**Written with the branch's own commit**, because this file's standing
rule is *when a PR is opened, give it a lane* — and a lane recording an
absorption belongs in the absorption, not after it. #171 drifted 153
commits while invisible here.
- **PR #238** — https://github.com/levineuwirth/pmacs/pull/238.
- **Branch `docs-absorb-237`**, base `githubsucks/main` @ `d038f71`
exactly. **`githubsucks/docs-absorb-237` is the authoritative tip** —
the ref, not a SHA.
- **Scope: `docs/active-work.md` and `docs/agent-handoff.md` only.** No
`src/`, no `pmacs-gpu/`, **no Stage 1a implementation** — verified with
`git diff --name-only githubsucks/main`, which lists nothing outside
`docs/`.
- **The recovery procedure was RE-RUN from an empty directory on git
2.55.0, not SHA-swapped**, and that is what licenses advancing the
base at all. It also **discharges the obligation left at `e67ad07`**,
where the base moved without the procedure being exercised. Details in
"Repository authority" above; the floor check was run against **both**
floors, and the documented two-argument worktree trap was reproduced
rather than assumed.
- **Gates: `./scripts/gate`, all eight stages green** (log
`20260812T111504Z-3265400`). No `--acceptance` and no `--protocol` —
docs only, so no suite is touched and no wire moves. That run covered
`502308d`. **Every commit after it is markdown-only** — stated as a
standing property rather than a count, because a count goes stale on
the next commit, which is how the previous version of this sentence
came to say "one commit, 34 lines" when there were two and 38. Check
it with `git diff --name-only 502308d..HEAD`, which must list nothing
outside `*.md`; `git diff --check` and `cargo fmt --check` are clean
at HEAD.
- **One judgement recorded because it exceeded the requested scope and
was approved on review**: §1a's board carried no GUI-arc row, which
contradicted the anchor two sections above it. The row sits where
`COHERENCE.md` §20 Q#GA5 puts the arc — after Priority 1, alongside
P2–P5, interacting only at the **P2 start gate** — and the section's
dateline now says which row is current and which are as of
2026-08-01.
- **THIS LANE MUST BE DELETED BY A FINAL PRE-MERGE COMMIT ON THIS
BRANCH, and cannot remove itself at merge.** GitHub merges the tree as
it stands, so "removed at merge" would land the words *PR #238 OPEN*
on `main` — a lane advertising an open PR that closed in the same
commit. It stays while the PR is under review, because an open PR
without a lane is the #171 defect; the last commit before merge takes
it out. Rule 4 removes it **outright** rather than rewriting it: it
describes a docs pass, not an arc.
## GUI arc Stage 1 — 1-pre MERGED as #237 (`d038f71`); 1a is next, NOT STARTED
**The lane is rewritten, not removed.** Rule 4 removes a lane when its
