chore: update dependencies and improve code formatting

- Added `vendor/discord-video-stream` to pnpm workspace.
- Refactored `llmModerationClient.ts` for better readability and consistency.
- Adjusted imports in `recordingsRoutes.ts` for clarity.
- Updated `webserver.ts` to correctly import `createRecordingsRoutes`.
- Enhanced test cases in `llmModerationClient.test.ts` for improved readability.
- Updated submodule references for `better-sqlite3`, `discord-video-stream`, `discord.js-selfbot-v13`, `drizzle-orm`, and `node-datachannel`.
- Created documentation for deprecated dependency removal plan and design.
