test: add E2E fixture app and dual-mode harness

Drives the release binary against a real SwiftUI/AppKit fixture and verifies
every effect by independent before/after observation — never the command's own
ok:true — so a command that reports success without an effect is caught. This is
the layer mock-adapter unit tests cannot cover: it exercises the contract
against the real macOS Accessibility API.

- AgentDeskFixture.swift exposes a fixed, diverse AX surface (native AppKit
  slider/stepper, gesture-only and ambiguous controls, a sheet, a press-toggled
  disclosure, async-appearing elements, a drag canvas). It is never tuned to
  make a command pass; a failure is a finding about the CLI or the harness.
- run.sh drives every ref-action command in BOTH headless and --headed mode with
  mode-specific target values, plus the double-click discriminator (headless
  fails closed with POLICY_DENIED, --headed completes) that proves the two modes
  differ. It also covers strict resolution, wait predicates, skeleton drill-down,
  sessions, trace redaction, surfaces, drag, expand, and force-close.
- The compiled fixture .app is a build artifact (gitignored; built on demand).

Run: cargo build --release && bash tests/e2e/run.sh (needs AX permission).

# End-to-End Tests (real binary vs. real app)
These tests drive the **release `agent-desktop` binary** against a **real macOS
application** and verify every effect by **independent observation** — never the
command's own `ok: true`. A command that returns success without producing the
effect is caught, because each check re-reads the UI (status label, element
value, scroll offset, `list-apps`, …) and asserts the observed `before`/`after`.
This is the layer that mock-adapter unit tests cannot cover: it exercises the
contract against the actual macOS Accessibility API.
## Layout
| Path | Role |
|------|------|
| `tests/fixture-app/AgentDeskFixture.swift` | SwiftUI + AppKit fixture exposing a fixed, diverse AX surface |
| `tests/fixture-app/build.sh` | Compiles the fixture into `build/AgentDeskFixture.app` |
| `tests/e2e/run.sh` | The harness: launches the fixture, runs the binary, asserts by observation |
The fixture is a **principal-engineer-grade slice of real UI**, not a target
tuned to make the CLI pass. It deliberately mixes AX-actionable native AppKit
controls (`NSSlider`, `NSStepper`) with gesture-only and ambiguous patterns. **A
failure here is a finding about the CLI or the harness — never a reason to edit
the fixture so the CLI passes.**
## Running
```bash
cargo build --release # the harness uses target/release/agent-desktop
bash tests/e2e/run.sh
```
Requirements:
- macOS with **Accessibility permission** granted to the terminal running the
harness (System Settings → Privacy & Security → Accessibility).
- The harness builds the fixture `.app` automatically if it is missing.
- `--headed` checks move the real cursor; run on a machine where that is OK.
Exit code is `0` when every scenario passes, `1` on any failure (with the
observed values printed inline for each failing check), `2` on setup error.
## What it verifies
- **Observation:** snapshot role diversity, `find` vocabulary + `roles_present`
hint, textarea→textfield alias.
- **Interaction in BOTH modes (the headless/headed contract):** every ref-action
command (`click`, `type`, `set-value`, `clear`, `check`, `uncheck`, `select`,
`set-value` on slider/stepper, `scroll`) is driven **twice** — default
**headless**, then **`--headed`** — with mode-specific target values so a
regression in either mode is caught by an independent `before`/`after`
observation. Headed must not regress the AX path (it is tried first); it only
adds cursor/physical fallbacks.
- **The headless/headed discriminator:** `double-click` on a gesture-only button
(no `AXOpen`) **fails closed with `POLICY_DENIED` headless**, and **completes
with `--headed`** (physical double-click). This is the crisp proof the two
modes differ and that `--headed` unlocks the physical fallback.
- **Strict resolution:** ambiguous twins do not silently act; a removed element
fails closed with `STALE_REF`.
- **Reliability core:** `wait` predicates (`enabled`, `actionable`, `visible`,
`value`), `wait --text` async appearance, skeleton traversal + scoped
drill-down, session isolation + session-independent explicit snapshots, trace
JSONL with secret redaction.
- **Surfaces / drag / expand / close:** open a sheet and act inside it,
source-tracked drag gesture verified by a tracking canvas, expand a
press-toggled disclosure, `close-app --force` verified via `list-apps`.
## Documented limitations (tracked, not failures)
- **Cross-target native drag-and-drop (`onDrop`)** needs the OS dragging-session
/ pasteboard protocol. Synthetic mouse events route mouse-up to the drag
origin, so they cannot drop onto a separate native target. Source-tracked
gestures (and web/Electron mouse-DnD) work; the harness verifies the gesture
via a tracking canvas.
- **SwiftUI `Slider`/`Stepper`/`DisclosureGroup` are not AX-actionable.** The
fixture uses native AppKit `NSSlider`/`NSStepper` (which are), so `set-value`
and `expand` are proven on controls that actually expose the capability.
## Adding a scenario
1. Expose the surface in `AgentDeskFixture.swift` with a stable
`accessibilityLabel` and a `statictext` status readout that reflects the
real state (so the harness can observe the effect, not the command's claim).
2. Add a check in `run.sh` using `verify <label> <status> <expected> <subcmd…>`
(mode-injected) or an explicit `before`/`after` + `assert` block.
3. If the command is a ref action, add it to `interaction_suite` so it is
covered in **both** headless and headed modes.
