Add Anti-Spam Discord bot

Introduce a new Anti-Spam Discord bot project. Adds project metadata and scripts (package.json, .env.example, .gitignore, README, deploy-commands.js) and the full src implementation: command registration and handling, per-guild settings persistence, configuration parsing, spam detection logic (phishing URLs, suspicious TLDs, mass/role mentions, image+URL combos, new account heuristics), and the bot entrypoint (index.js) that enforces permissions, logs actions, and optionally bans offenders. README explains setup, required intents, and usage; per-server settings are stored under data/guild-settings.json. (package-lock.json added for dependency resolution.)
