Refactor: PHP-Built-in-Server durch TypeScript-Binary (Bun Runtime) ersetzt

- src/*.ts: Port von mcp/*.php (helpers, tools, server)
- Bun.serve() statt php -S — production-grade HTTP, POST funktioniert
- dist/mua-1.0.0-x86_64-1.txz: Slackware-Paket (Binary + rc.mua + mua.page + PHP-Helper)
- plugin/mua.plg: .txz-Installation via upgradepkg
- scripts/rc.mua: Binary statt php -S
- scripts/mua.page: Binary-Info statt PHP-Version
- scripts/package.sh: .txz-Builder

Fix: MCP-POST-Endpunkt lieferte leeren Body (php -S Limitation).
Bun.serve() löst das Problem.
