test(e2e): add Playwright spec for /play Bevy canvas route

play_canvas.spec.js covers the window.__FERROUS_DEBUG__ bridge on the
/play route (five tests): bridge availability + seed param, draw3 URL
param, applyLegalMove/undo round-trip, failureReport schema, and
autonomous autoplay invariant batch across 7 seeds.

All tests drive exclusively through the debug bridge — no DOM selectors,
because the Bevy canvas is a single <canvas> element with no HTML
controls.

Also update SESSION_HANDOFF.md to reflect post-v0.35.1 work (10 commits
since 2026-05-18 handoff), new e2e architecture notes, and HiDPI fix doc.

## Current state
- **HEAD on origin/master:** `8f86d66` (fix: three leaderboard bugs)
- **HEAD:** `play_canvas.spec.js` added (Playwright tests for `/play` Bevy canvas route)
- **Latest tag:** `v0.35.1`
- **Working tree:** clean
- **Build:** `cargo clippy --workspace -- -D warnings` clean
- **Tests:** 1277 passing / 0 failing across the workspace
- **Tests:** 1243 Rust tests passing; Playwright suite in `solitaire_server/e2e/`

## What shipped since the last handoff (v0.35.1 → present, 2026-06-02)
| Commit | Summary |
|--------|---------|
| `64f975e` | 14 cross-platform UX/UI fixes from 500-game audit |
| `763fdb4` | Fix input: hit-test deck at correct position; accept waste click |
| `1cdb78c` | cargo fmt; add analytics domain to CSP |
| `baf524e` | Rebuild Bevy canvas WASM; add SolitaireGame interactive API |
| `9ff0585` | Remove Quaternions registry auth; canvas WASM drift guard |
| `de7ae16` | Delay first-run modal until splash screen despawns |
| `8b736ca` | Debug drag failures (temp logging, removed in next commit) |
| `8b262af` | Clamp wgpu surface to CSS pixels on HiDPI (prevented WASM panic) |
| `d45b7cb` | Add Playwright e2e test suite for web routes |
| `2cf7282` | Add `window.__FERROUS_DEBUG__` bridge to `/play` for automation |
**Key audit bugs fixed (all 7 from 500-game UX audit):** timer-after-undo, radial-menu clamping, Android resume flash, tab-hidden timer, orphaned tmp files, drag threshold 4→6px, Draw-1 recycle doc comment.
**HiDPI wgpu fix:** `WindowResolution::default().with_scale_factor_override(1.0)` added to the Bevy canvas app. Root cause was physical pixels (CSS×DPR) exceeding WebGL2's 2048px per-dimension limit on HiDPI displays.
**E2E test architecture:** three-tier — Rust unit tests → Playwright smoke/review specs → cycle regression gate. Debug bridge contract in `docs/testing-architecture.md`.

- **Test input-state pitfall:** `MinimalPlugins` has no input-tick system, so
`ButtonInput::just_pressed` state persists across frames unless explicitly cleared
with `input.release(key); input.clear()` between updates.
- **`/play` debug bridge design:** `play.html` runs two independent WASM instances in
`Promise.all([bootstrap(), init()])`. `bootstrap()` sets `window.__FERROUS_DEBUG__`
(logic layer via `solitaire_wasm.js`); `init()` starts the Bevy canvas. The bridge
operates its own `SolitaireGame` — moves applied through the bridge do NOT affect
the Bevy visual game. This is intentional for automation/invariant checking.
- **HiDPI Bevy canvas:** `WindowResolution::default().with_scale_factor_override(1.0)`
is set in the canvas app. Without this, physical pixels exceed WebGL2's 2048px limit
on HiDPI displays, causing an immediate wgpu panic on the first resize event.
- **`/play-classic` vs `/play` in e2e:** `smoke.spec.js` + `gameplay_review.spec.js`
target `/play-classic` (DOM-heavy game.html); `play_canvas.spec.js` targets `/play`
using only the `__FERROUS_DEBUG__` bridge (no DOM selectors). `cycle_metrics.js`
supports both via `--route play-classic|play`.
