Simplify WebGL renderer integration: remove dead extension code, untangle GameView naming (#4240)

## Summary

The WebGL renderer was adapted from an external extension and carried a
lot of machinery this integration never uses (replay playback, its own
input/event system, a GL radial menu). This PR is two mechanical cleanup
passes with **no behavior change**: delete the dead code, then untangle
the `GameView` naming collision.

**78 files, +142 / −2,197.**

### Pass 1 — remove dead extension baggage

- **Replay/copy mode**: `FrameData.tileMode` was hard-coded `"live"`;
the copy branches in `frame/Upload.ts`, `UploadOptions` (never passed),
`applyFullFrame`/`applyFullTiles`/`applyDelta` on the facade and
`GPURenderer`, `HeatManager.resetForSeek`, and the seek-upload methods
on `TerritoryPass`/`TrailPass` were all unreachable. Also deletes
`types/Replay.ts`, `types/FrameSource.ts`, `types/GameUpdates.ts`,
`types/Game.ts` (imported only by the types barrel).
- **FrameEvents**: trimmed from 14 fields to the 3 actually populated
and read (`deadUnits`, `conquestEvents`, `bonusEvents`). The other 11
fed the extension's stats system and were never written or read here.
- **GL radial menu**: `RadialMenuPass`, its 4 shaders, and ~10 API
methods on facade + renderer had zero callers — the game uses the DOM/d3
radial menu in `hud/layers/RadialMenu.ts`. The pass was constructed and
drawn every frame for nothing.
- **Facade event system**: `GameViewEventMap` defined 10 event types
(`click`, `hover`, `scroll`, …) but only `contextrestored` was ever
emitted — input actually flows through `InputHandler` → EventBus →
controllers. Replaced the listener map with a single `onContextRestored`
callback and deleted `Events.ts`. Also fixed the stale header comment
claiming the facade handles user interaction.
- **Unused API surface**: removed ~20 facade/renderer methods with zero
callers (camera passthroughs like
`panTo`/`zoomTo`/`fitMap`/`screenToWorld`, hit-testing queries, SAM
replay setters, `setSelectedUnit`, `clearFx`/`setFxTimeFn`,
`onFrame`/`afterRender`/fps tracking).

Deliberately left alone: `Camera`'s pan/zoom primitives (building blocks
for a possible future camera unification) and the `timeFn` plumbing
inside the FX passes (deeply embedded as defaults; only the dead
renderer-level wrappers were removed).

### Pass 2 — untangle the three GameViews

- `render/gl/GameView.ts` → **`MapRenderer.ts`** (class `MapRenderer`).
Every importer was already aliasing it as `WebGLGameView` to dodge the
collision with the simulation-mirror `GameView` in `client/view/`, so
this removes aliasing rather than adding churn. `render/CLAUDE.md`
updated.
- Deleted the `src/core/game/GameView.ts` back-compat shim (its own TODO
asked for this). All 51 importers now import from `src/client/view/`
directly via a new 3-line barrel `view/index.ts`.

## Test plan

- `tsc --noEmit` clean, `eslint` clean
- Full test suite passes (1,385 + 65 server tests)
- Manual verification via headless Chromium: started a singleplayer game
and confirmed the renderer works end-to-end — terrain draws, spawn-phase
overlay shows, territories fill with borders after spawning, player
names/flags render, no renderer console errors
