Manual smoke — F4 propose/accept (live turn)

Pre-req: Claude Code installed + signed in (the claude-code provider rides that login — the extension holds no credentials, INV-8). Run on a real machine, not CI.

1. npm run build, then F5 (the EDH opens the committed sandbox/ playground).
2. Open playground.md, select a sentence → right-click → Ask Claude to Edit Selection → give an instruction.
3. ✅ A proposal appears: the selection gets an amber tint and a "Claude proposes" comment thread shows a diff of current → proposed. The document text is unchanged (INV-10).
4. Click ✓ Accept Proposal in the thread title. ✅ The replacement lands and renders Claude-tinted (the F3 attribution substrate); the proposal disappears.
5. Repeat with another selection and click ✗ Reject Proposal. ✅ The document is untouched; the proposal disappears.
6. Propose again, then save and reload the window. ✅ The pending proposal is restored at its re-resolved range.
7. Failure path: edit the proposed-on text, then try Accept. ✅ Refused with a warning ("target text changed"); undo your edit → Accept works.
