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).
