refactor: migrate messageStore to drizzle-orm

- Replace all raw SQL queries in messageStore.ts with Drizzle ORM queries
- Remove DatabaseAdapter dependency from messageStore functions
- Update all function signatures to be async and remove db parameter
- Functions now use getDatabase() internally for database access
- Update all call sites in messageCapture.ts, attachmentUploader.ts, aiAnalyzer.ts, webserver.ts, and index.ts
- All functions remain backward compatible in behavior
- TypeScript typecheck passes with no errors
- All tests pass (11 passed)

+# Drizzle ORM Migration Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** Replace raw SQL queries and manual database adapter with Drizzle ORM, providing type-safe database operations, automatic migrations, and better maintainability while supporting both SQLite and PostgreSQL.
+
+**Architecture:** Replace the custom DatabaseAdapter pattern with Drizzle ORM's unified API. Define schema using Drizzle's TypeScript schema definitions. Replace all raw SQL queries in muxer-queue.ts and messageStore.ts with Drizzle query builder. Use Drizzle migrations for schema management. Maintain backward compatibility with existing data.
+
+**Tech Stack:** drizzle-orm, drizzle-kit, better-sqlite3 (SQLite), postgres (PostgreSQL), TypeScript
+
+---
+
+## File Structure
+
+**New files to create:**
+- `src/database/schema.ts` — Drizzle schema definitions for all tables
+- `src/database/drizzle.ts` — Drizzle database client initialization
+- `drizzle.config.ts` — Drizzle Kit configuration
+- `drizzle/migrations/` — Auto-generated migration files
+
+**Modified files:**
+- `src/muxer-queue.ts` — Replace raw SQL with Drizzle queries
+- `src/moderation/messageStore.ts` — Replace raw SQL with Drizzle queries
+- `src/database/adapter.ts` — Remove (no longer needed)
+- `src/database/postgres.ts` — Remove (Drizzle handles this)
+- `src/database/migrations.ts` — Remove (Drizzle handles this)
+- `src/index.ts` — Update database initialization
+- `src/webserver.ts` — Update database calls
+- `package.json` — Add drizzle-orm, drizzle-kit dependencies
+- `src/config.ts` — Keep PostgreSQL config variables
+
