🧪 Verifier: Add tests for discordAdapters

[google-labs-jules]

🎯 Goal
Increase test coverage for packages/bot/src/core/discordAdapters.ts by ensuring that adaptGuild and buildVoiceChannelsSnapshot functions are fully tested.

🧪 Test Strategy
Created a new test file packages/bot/tests/discordAdapters.test.ts. Mocked out discord.js Guild and VoiceChannel dependencies entirely by crafting specific fixture objects and mapping them with as unknown as [Type]. Asserted on the correctness of filtering logic (e.g., bot counting vs. user counting) and lazily evaluated getters for Voice Channels.

🛡️ Safety

• The packages/bot/tests/discordAdapters.test.ts file operates entirely in memory using standard Javascript logic and explicit test objects.
• It doesn't connect to Discord API.
• All existing tests pass successfully.
• Code conforms strictly to @typescript-eslint/no-explicit-any by typecasting with as unknown as DjsGuild.
