Raycast Pro

Build me a Mac command palette covering the parts of Raycast Pro I actually use: clipboard history, snippets, and AI commands. Requirements: - An Electron tray app with a global hotkey (alt+space) opening one centered input window; electron-store for settings, better-sqlite3 for data. - Clipboard history: watch the clipboard, keep the last 500 text entries with timestamp and source app, fuzzy-search them with fuse.js, Enter pastes the selection. - Snippets: a snippets.json of {keyword, expansion}; picking one copies the expansion with {date} and {clipboard} placeholders filled in. - AI commands: Fix Grammar, Summarize, and Translate run the current clipboard through an LLM (key in .env) and put the result back on the clipboard with a notification. - Custom commands: shell scripts in a commands/ folder appear in the palette by filename; their output is copied or shown. - Everything local except the LLM calls; no accounts, no telemetry. - Out of scope: an extension store, file search, window management, and cloud sync. Do not chase native launcher speed, this is Electron and that is the tradeoff. - README: the macOS accessibility permission needed for paste simulation, and how to change the hotkey.
