✨ feat(radar-map): add GTA-style circular radar map with rotating compass

[leandroruel]

Summary

Addresses the two issues raised in #7:

• Removed old MiniMap — the bottom-right legacy mini-map has been fully removed (dynamic import + JSX); only the new RadarMap remains
• Rebased on current main — merged upstream/main (includes pixels system, E.Arcade, compare cinematic, wallpaper mode, sponsor landmarks, and all other recent features)

What this adds

• New RadarMap component (bottom-left): canvas raster layer renders building dots per district + SVG overlay for player position, camera field-of-view cone, N/S/E/W cardinal labels, and circular bezel ring
• Heading-up rotation: map rotates with camera direction using a shortest-arc normalization algorithm to prevent CSS transition wrap-around flips at the ±180° boundary
• Camera position tracking in OrbitScene: useFrame throttled to every 6th frame (~10fps) via onCameraMove prop
• District-aware coloring: buildings colored by district; current district highlighted
• Compass readability: N/S/E/W labels counter-rotated via SVG transform so they stay upright as the map spins
• Visibility: radar only appears after user enters the city (exploreMode || flyMode)

Files changed

File	Change
src/components/RadarMap.tsx	New component
src/components/CityCanvas.tsx	Added onCameraMove prop to OrbitScene; merged with upstream new props (focusPosition, isCompareCinematicPlaying, wallpaperMode, etc.)
src/app/page.tsx	Removed MiniMap; wired RadarMap + cameraPos/playerYaw state

Test plan

• Title screen → RadarMap should NOT appear
• Click "Explore City" → RadarMap appears bottom-left
• Rotate camera → map rotates heading-up (like GTA radar)
• Fly mode → radar shows player yaw heading
• Confirm old bottom-right mini-map is gone
• All upstream features (E.Arcade, pixels, compare cinematic, wallpaper) still work

Hey @leandroruel, thanks for the awesome RadarMap contribution! Really well done with the heading-up rotation and district-aware coloring.

I cherry-picked your commit into main (with Co-authored-by attribution) and built on top of it — added remote pilot blips so you can see other players flying on the radar, repositioned it to bottom-right, and removed the legacy MiniMap.

Closing this PR since the changes are already merged. Thanks again for the contribution! 🙌
