Recolor example app icons to brown; mark the 1.0.0 release

[cameronapak]

Summary

The example app's icon set moves from red to brown across iOS, Android, splash, and web. A major changeset marks both published packages for the 1.0.0 milestone release — there are no API changes, the bump is symbolic.

Changes

1. Recolored the example app icon set from red to brown — iOS light/dark, Android adaptive foreground + background image, splash, and favicon — via a +36° hue shift that preserves the glyph and gloss (grayscale tinted/monochrome untouched; the OS colorizes those at runtime).
2. Updated Android adaptiveIcon.backgroundColor from #c5515a to #aa673a so the flat background matches the recolored background image.
3. Added a major changeset marking both published packages for the 1.0.0 launch (no breaking API changes).

Start here: change 3 — the major bump is intentional and symbolic (the 1.0.0 launch marker), not a real breaking change; consumers have nothing to migrate.

Before	After

Test plan

• expo prebuild (iOS + Android): generated AppIcon.appiconset (light/dark/tinted) and Android mipmaps with iconBackground = #aa673a.
• expo run:ios: build succeeded, app installed and launched on the iOS Simulator.
• pnpm changeset status: both published packages bump major → 1.0.0; example stays private (unpublished).

Greptile Summary

This PR recolors the example app's icon set from red to brown across iOS, Android, splash, and web assets, and adds a major changeset to mark the 1.0.0 milestone release for both published packages.

• Updated six PNG assets (main icon, dark icon, adaptive foreground/background, splash, favicon) with a +36° hue shift; grayscale tinted and monochrome variants are correctly left untouched since the OS colorizes them at runtime.
• Changed adaptiveIcon.backgroundColor in app.json from #c5515a to #aa673a to keep the flat fallback color consistent with the recolored background image.
• Added a major changeset for @youversion/platform-react-native-expo-core and @youversion/platform-react-native-expo-ui; the description clearly notes there are no breaking API changes and the bump is a symbolic 1.0.0 launch marker.

Confidence Score: 5/5

Safe to merge — changes are limited to example app assets, a single hex color in app.json, and a changeset file; no SDK source code is touched.

The diff is entirely asset swaps and a config hex-color update in the example app, plus a well-documented changeset. The grayscale/monochrome icon variants are correctly left untouched. The backgroundColor in app.json aligns with the new background image. No logic, API surface, or native source code is modified.

No files require special attention.
