Initial implementation of TriggerShell

A Python CLI (typer) that bootstraps Node/pnpm and launches a Next.js 16 web
app for running configured shell scripts: YAML config validated by a shared
Zod schema, dynamic per-script forms mapped to shadcn controls, argv-safe
execa execution with live WebSocket streaming, SQLite/Drizzle run history,
and optional argon2 session + API token auth.
