fix(map): disable imagery footprint stroke to prevent Intel GPU shader crash

[koala73]

Summary

• PolygonLayer with getLineColor causes deck.gl to spawn an internal PathLayer stroke sublayer
• Its fragment shader (satellite-imagery-layer-stroke-fragment) fails to compile on Intel integrated GPUs (i11-series, Windows 11), crashing the orbital surveillance / satellite imagery layer
• Fix: set stroked: false — removes the stroke sublayer entirely, eliminating the shader compilation failure

Fixes #2518

Test plan

• Verify satellite imagery footprints still render (translucent fill) on all GPU types
• Confirm no WebGL errors in console on Intel GPU (Windows)
• npm run typecheck passes

Greptile Summary

This is a targeted one-line fix to createImageryFootprintLayer in DeckGLMap.ts that prevents a WebGL shader compilation crash on Intel integrated GPUs by disabling the PolygonLayer stroke sublayer entirely.

Key changes:

• Removes getLineColor and lineWidthMinPixels from the satellite imagery footprint PolygonLayer
• Adds stroked: false, which prevents deck.gl from spawning the internal PathLayer stroke sublayer whose fragment shader was failing to compile on Intel i11-series GPUs (Windows 11)
• The translucent fill ([0, 180, 255, 40]) is preserved — footprint polygons remain visible

Trade-off: The visible blue outline ([0, 180, 255, 180]) around imagery footprints is intentionally sacrificed in exchange for cross-GPU compatibility. This is a reasonable trade-off given that the stroke sublayer was crashing the entire layer on affected hardware.

Confidence Score: 5/5

Safe to merge — minimal, correct fix with no logic regressions; intentional visual trade-off is well-documented

The change is two lines removed, one line added. It correctly uses deck.gl's documented stroked: false flag to prevent sublayer creation, directly addressing the root cause of the Intel GPU crash. No logic changes, no type errors, and the test plan covers the relevant regression surfaces.

    Note over App,GPU: Before this PR
    App->>PL: new PolygonLayer({ getLineColor, lineWidthMinPixels })
    PL->>SL: auto-spawns internal stroke sublayer
    SL->>GPU: compile satellite-imagery-layer-stroke-fragment shader
    GPU-->>SL: ❌ shader compilation failure (Intel i11 / Win11)

    Note over App,GPU: After this PR
    App->>PL: new PolygonLayer({ stroked: false })
    PL-->>SL: no stroke sublayer created
    PL->>GPU: compile fill shader only
    GPU-->>PL: ✅ renders translucent fill correctly
