F10 (#29) made the rendered preview the single review surface and hid the F6
two-pane vscode.diff view (command + ctrl+alt+d set when:false). This removes
that now-unreachable view code:
- DiffViewController: drop toggle/findDiffTab/epochLabel/isDiffOpen, the
`cowriting-baseline:` TextDocumentContentProvider + BASELINE_SCHEME + baselineUri
+ the content-provider change emitter, and the toggleDiffView command. The
baseline DATA layer is fully intact — ensureBaseline/advance/pin/capture,
getBaseline, baselineFilePath, onDidChangeBaseline, persistence (INV-19), and
the machine-landing auto-advance (INV-18) that F7/F10 consume.
- package.json: remove the toggleDiffView command, its commandPalette entry, and
the ctrl+alt+d keybinding.
- E2E: diffView suite keeps the baseline-data-layer tests, drops the two-pane
view tests; the F10 + no-workspace suites assert toggleDiffView is now absent
(was: declared-but-hidden).
Deliberate deviation from the issue's literal acceptance: pinDiffBaseline is
KEPT. The canonical Solution Design (coauthoring-interactive-review.md §6.7)
scopes the removal to the two-pane VIEW only ("keep the controller + baseline
store"); pin() lives in the baseline lifecycle (§6.4), never touches vscode.diff,
and is exercised by live F7 baseline-reset tests. Where the P3 capture draft and
the approved spec conflict, the spec wins (documentation-leads-automation).
194 unit + 49 E2E green; typecheck + build clean. No F7/F10 behavior change.

F6 no longer requires a workspace file. It gets its own diffable predicate
(any file: or untitled:) decoupled from F2 isTracked, keys baselines by a
sha256 of the document URI, and stores them in VS Code GLOBAL storage
(context.globalStorageUri) — always present, never the repo (INV-19). Untitled
buffers have no durable identity → in-memory baseline only (lost on reload).
DiffViewController is now constructed before the workspace-root check and its
commands are always live (never stubbed) — the machine-landing advance wiring
stays in the with-root branch since the seam only fires on workspace files.
BaselineStore generalized to key-by-hash (Baseline.docPath → uri).

F6 §6.5 PUC-1. Detects the baseline diff tab (original scheme cowriting-baseline,
modified == the doc) to close-and-reveal; else opens vscode.diff with an epoch
title. Live document on the right — editor state preserved by construction.

F6 §6.2/§6.4, INV-18/INV-19. ensure/advance/pin capture buffer text, persist
via BaselineStore, refresh the open diff via onDidChange. Storage-unavailable
degrades to in-memory + one warning. toggle UX lands in SLICE-3.
