- Remove pnpm workspace, moon repo, and all monorepo tooling - Delete packages/shared/, embed shared code directly into each service - Copy packages/shared/src/* -> services/backend/src/shared/ and services/discord-gateway/src/shared/ - Replace all @bete/shared imports with @/shared/ path alias - Remove @bete/shared workspace dependency from both services - Update root package.json scripts from --filter to --prefix - Rewrite Dockerfiles to build each service standalone - Clean up biome.json, .gitignore, remove root drizzle.config.ts
