A Raycast extension for quotes and portfolio

[iamsaquib8]

What

Raycast's store is a discovery channel for macOS developers. A small extension that shells out to stockwise ... --json gives quick quotes and a portfolio glance from the launcher. This is part of the "Editor and launcher extensions" roadmap idea.

Design

• Commands: "Quote" (type a symbol, see price, day change, 52-week range), "Portfolio" (value, day P&L, top movers), "Watchlist".
• Uses the installed stockwise binary (quote --json, portfolio --json, watch --json); shows install help if it is missing.
• Lives in raycast/extensions once published; develop it in integrations/raycast/ here first.

Done when

• The extension is accepted into the Raycast store.
• It depends only on documented --json shapes (json: unify _pct/_percent, document 0.7 shapes, add JSON errors #223).
