feat(ux): unify "Ask Claude to Edit" + inline prompt at selection; fix keybindings

Operator feedback on the Ask-Claude ergonomics (relates to #42/#43/#60):

- One user-facing command `cowriting.edit` ("Ask Claude to Edit") routes to the
  selection or whole-document flow at runtime via the pure `routeEdit` helper
  (selection → editSelection; none / tab right-click → editDocument). The two
  underlying commands stay registered for the seams + E2E but are hidden from the
  palette, and the split menu pairs collapse to one entry.
- Keybindings with `mac` variants (the missing variant is why ⌃⌥R "didn't work"
  on macOS — Option combos are unreliable there): `cmd+alt+e`/`ctrl+alt+e` for
  Ask-Claude-to-Edit, `cmd+alt+r`/`ctrl+alt+r` for the review panel.
- The instruction prompt now renders INLINE at the selection/cursor via a
  dedicated Comments-API controller (`InlineAskController`, `cowriting.askClaude`)
  instead of the top-center QuickInput — VS Code's Inline-Chat-style placement.
  Both Ask-Claude entry points (editSelection + the preview's askClaude) share it.

Tests: routeEdit unit tests; E2E menu/palette assertions updated for the unified
command; E2E drives the inline prompt by stubbing `api.inlineAsk.prompt`.

+`/wgl-planning-and-executing implement #60 (live turn progress) from coauthoring-live-progress.md`
+
+(Continuation of brainstorming session 0055, which graduated the spec; the
+operator said "implement it" → this coding session.)
+
+## Plan
+
+Plan + execute **#60** (P1 feature — live turn progress) from the graduated
+Solution Design `coauthoring-live-progress.md`. Four cuts: (1) pure
+`turnProgress.ts` reducer + tests; (2) `runEditTurn` + `onProgress`/`AbortSignal`;
+(3) `liveProgressUi` + setting + both call sites; (4) host-E2E + smoke.
+Branch `s60-live-progress` → PR → main.
+
+## Pre-state
+
+- Clean `main` at session start (fast-forwarded 13 commits — the sessions/ repo
+  is the code repo itself). Baseline: 222 unit green.
+- #60 has a graduated Solution Design → §4.3 R2(b) satisfied.
+
+## Session arc
+
+1. **Claim + plan.** Claimed 0056 (no in-flight). Wrote the implementation plan
+   with `superpowers:writing-plans` → `docs/superpowers/plans/2026-06-26-live-turn-progress.md`
+   (self-reviewed: full spec coverage, no placeholders). Grounded in the exact SDK
+   types (`AgentToolCallPart.toolName`, `AgentUsage.inputTokens+outputTokens`), the
+   vitest/host-E2E patterns, and the injectable `editTurn` seam. Branch
+   `s60-live-progress`.
+2. **Task 1 — pure reducer.** `src/turnProgress.ts` + `test/turnProgress.test.ts`
+   (13 cases). Fixed the type-only event import: `AgentRuntimeEvent` is exported
+   from **`@cline/shared`**, not `@cline/sdk` (which doesn't re-export it) — caught
+   by typecheck; amended the commit.
+3. **Task 2 — `runEditTurn`.** Added `RunEditTurnOptions {onProgress, signal}`;
+   subscribes to the agent, folds events through the reducer, wires `signal` →
+   `agent.abort()`; `finally` unsubscribes. Mocked-agent unit tests (vitest
+   `doMock` intercepts the dynamic import).
+4. **Task 3 — host relay.** `src/liveProgressUi.ts` (notification line +
+   "Cowriting: Claude" OutputChannel, reveal gated by setting) + `package.json`
+   `contributes.configuration` `cowriting.liveProgress.revealOutput`.
+5. **Tasks 4+5 — both call sites.** `editSelection` (extension.ts) and preview
+   `askClaude`/`runEditAndPropose` (trackChangesPreview.ts) made cancellable,
+   relaying via the shared `liveProgressUi`; widened the `EditTurn` seam to accept
+   `opts?` (back-compat). Added `liveProgressUi` to `CowritingApi`.
+6. **Task 6 — host E2E.** `test/e2e/suite/liveProgress.test.ts`: progress is
+   additive (INV-44), aborted turn proposes nothing (INV-47).
+7. **Task 7 — verify + smoke.** typecheck + 237 unit + build green; enhanced
+   `scripts/smoke-live-turn.mjs` to log progress.
+8. **Subagent review.** Found a **Medium** (a pre-aborted `AbortSignal` was a
+   no-op — `agent.abort()` runs before the SDK's AbortController exists, so the
+   turn ran to completion) + a **Low** (a throwing `onProgress` relay could fail
+   the turn). Fixed both: short-circuit (throw) before `run()` on a pre-aborted
+   signal; wrap the relay in try/catch. Strengthened the unit + E2E to prove it.
+9. **Ship.** Pushed; opened PR #61; operator approved merge despite the
+   concurrency (below). Squash-merged `644885c`; issue #60 auto-closed.
+
+## ⚠️ Concurrency event (mid-session)
+
+Partway through, the shared working tree gained **uncommitted changes this session
+did NOT make** — a `cowriting.edit` / `routeEdit` reach refactor across
+`src/workspacePath.ts`, `test/workspacePath.test.ts`, and the menu/`routeEdit`
+parts of `package.json` + `src/extension.ts`. It broke 3 E2E (`f12Reach` ×2,
+`f11Toolbar` ×1) that still expect the old `editSelection`/`editDocument` command
+surface. Handling: committed **nothing** of it, discarded **nothing**; verified
+#60 green in isolation by stashing it (by path, reversible) — 237 unit + both #60
+E2E pass, only the documented `F10 #38` undo-sandbox flake remains — then popped
+the stash to restore it. Surfaced to the operator, who chose to merge #60 (its 7
+commits are isolated; the PR diff contains none of the foreign WIP).
+
+## Cut state (at finalize)
+
+- **#60 merged** to main (PR #61 squash `644885c`); issue #60 closed.
+- **Plan archived:** `submit-plan.sh` → content repo `plans/2026-06-26-live-turn-progress.md` (`22ec57e`).
+- **Foreign refactor WIP:** still uncommitted in the working tree, untouched —
+  for whoever is doing it to continue/commit (it rebases onto the new main).
+- **Local tree:** left on branch `s60-live-progress` (merged) DELIBERATELY — a
+  `checkout main`/`pull` would have disturbed the foreign uncommitted WIP. Local
+  main not synced; origin/main has #60. Operator should reconcile the local tree
+  + the in-flight refactor.
+- **Memory:** added `session-0056-60-live-progress-shipped.md` + index line.
+
+## Next-session prompt
+
+```
+/wgl-planning-and-executing reconcile the local tree (sync main; land/branch the in-flight cowriting.edit/routeEdit refactor), then pick the next item (open: #59 P1 bug, #57, #58, #32, #35, #40, OQ-2)
+```
+
+## Deferred decisions
+
+- **Left local on `s60-live-progress` (did not sync main):** to avoid disturbing
+  the concurrent uncommitted refactor in the shared tree. Low confidence this is
+  the tidiest end state, but it is the safest for the foreign WIP. Operator to
+  reconcile.
+- **Token field for the activity line:** used `inputTokens + outputTokens` from
+  `AgentUsage` (no `totalTokens` field exists). Cache tokens excluded.
+- **OutputChannel append-not-clear + auto-reveal gating:** per spec §3.5; carried
+  from session 0055's confirmed sub-decisions.
