Add Discord Rich Presence

[SunkenInTime]

Summary

• add Windows Discord Rich Presence for the strategy library and open strategies
• publish privacy-safe map, side, and live board counts without strategy names
• use Discord-hosted map thumbnails with the Icarus logo as the app badge
• add a persisted Privacy setting to disable presence
• debounce board updates to stay within Discord rate limits

Why

Icarus previously had no Discord activity integration. This adds an optional local RPC connection using the public Discord application ID; no client secret or user authentication is embedded in the app.

User impact

Discord can now show whether the user is browsing the library or planning on a particular Valorant map and side. Open strategies also report agent and ability counts, while strategy names remain private.

Validation

• dart run build_runner build --delete-conflicting-outputs
• dart analyze lib/services/discord_presence_service.dart lib/main.dart lib/providers/user_preferences_provider.dart lib/widgets/settings_tab.dart test/discord_presence_service_test.dart
• flutter test test/discord_presence_service_test.dart
• flutter test (328 tests passed)
• manually verified the live Discord card on Windows for the library and Split attack strategy states
