Clip view cones to Valorant map geometry

[SunkenInTime]

What changed

• Added compact, generated VisionGeometry assets for every current map.
• Clips free and agent-attached view cones with event-ray visibility polygons against the selected map/elevation layer.
• Mirrors occluders with attack/defense side switching.
• Persists a per-cone View elevation override with undo/redo and strategy migration support.
• Uses Riot's exported elevation slices for 12 maps; Summit uses a deterministic boundary fallback generated from its current Icarus even-odd SVG because the available game export predates Summit.
• Aligns the stale folder-icon migration marker with app version 92 so the repository's required full-suite CI check can pass.

Why

The previous painter rendered only a radial wedge, so cones bled through walls and outside map boundaries and could not choose the correct stacked-floor occluders.

Performance / impact

• Geometry JSON is decoded off the UI isolate and cached per map.
• Ray candidates are range-AABB filtered, with 2° arc samples plus endpoint/circle event rays to avoid corner leaks.
• Generated assets total about 405 KiB.
• Worst-case Summit fallback measured about 6.7 ms per cone computation in debug JIT on the development machine.

Verification

• fvm flutter analyze — only the existing pages_bar.dart:514 deprecated-onReorder info.
• fvm flutter test — all 262 tests pass.
• New tests load all 13 map assets, verify defense mirroring, mirrored position/rotation symmetry, wall clipping, range arcs, corner event rays, and elevation serialization.
• Generated all exported geometry assets from D:\Downloads\Output\Exports\ShooterGame.
• Visually exercised the Windows editor with an isolated strategy; the Ascent 103° cone stops at the displayed corridor/wall boundaries.

Greptile Summary

This PR adds map-aware clipping for Valorant view cones. The main changes are:

• Generated compact vision geometry assets for each current map.
• Ray-cast visibility polygons for free and agent-attached cones.
• Defense-side geometry mirroring and per-cone elevation overrides.
• Persistence, undo/redo, and migration support for view elevation.
• Supporting tests for geometry loading, mirroring, clipping, and serialization.

Confidence Score: 5/5

This looks safe to merge.

• No blocking issues found in the changed code.

[SunkenInTime]

@greptileai please re-review the latest head. The free-cone rotation now falls back to the persisted utility rotation, and the side-switch coordinate-frame invariant is documented and covered by a mirrored origin/rotation clipping regression test.

[SunkenInTime]

@greptileai final re-review please: the latest head only aligns the pre-existing folder-icon migration marker with app version 92. The complete repository suite now passes (262/262).

[SunkenInTime]

Verified and fixed the Windows long-worktree build failure in 8ef6296. The WebView dependency target now uses a shorter Visual Studio project label, and a full debug build succeeds from the original nested path.\n\n@greptileai please review the latest head.

@greptileai please review the latest head. This update adds topmost navigation-height inference, automatic Riot elevation-slice selection, hybrid Riot blocker plus SVG boundary clipping, and a calibration overlay. The full local suite passes (269/269).
