Task 2 of the native-surfaces migration plan. GitBaselineAdapter resolves a
document's HEAD blob via the built-in vscode.git extension (hardened with a
.git/logs/HEAD watch that nudges repo.status(), since the git extension's own
watcher doesn't reliably notice out-of-band commits on non-workspace-folder
repos in the E2E host). DiffViewController is reworked into a baseline router:
head mode (git-tracked, never persisted, re-read on commit) vs snapshot mode
(captured on CoeditingRegistry entry, re-pinned by "Mark Changes as Reviewed"
— renamed from cowriting.pinDiffBaseline, D14). The shipped machine-landing
baseline advance (#48/INV-18) is retired: a landed Claude edit now stays a
visible change-since-baseline until commit or review (INV-7/D21). Legacy
on-disk reasons ("opened"/"machine-landing") migrate to "entered" via
BaselineStore.normalizeReason on load.

Adds test/e2e/suite/f10Review.test.ts covering the F10 flow: open preview
(mode "on", fresh baseline all-unchanged), type → cw-by-human span, propose →
cw-proposal block with ✓/✗, accept → lands + baseline advances + block clears,
reject → vanishes + doc untouched, toggle off → renderPlain has no cw- marks,
status-bar PUC-6 (indicator with no panel, hidden once opened), and the
clean-editor INV-32 facts (retired toggleAttribution, F6 ctrl+alt+d hidden).
Rewrites the obsolete F9 authorship-mode test as an F10 review test
(cw-by-claude in the on-state render; getMode defaults to "on"). Updates
attribution.test.ts (drops the retired isVisible/toggleAttribution toggle,
asserts the toggle is gone) and noWorkspace.test.ts (toggleAttribution +
acceptProposal/rejectProposal are retired, preview-only — INV-32).
Honesty fix in the status-bar seam: hideStatus() clears statusItem.text so
statusText() reports undefined when the indicator is hidden (it previously
returned its stale last value after a panel opened).
