Dispatch v0.6.1

A quick follow-up to 0.6.0.

• Faster startup. Rarely used features (runner, mock servers, vault, load tests, request chains, gRPC, the command palette, importers, cookies, the AI assistant, compare and others) now load the first time you open them. The app starts with 27 modules (350 KB) instead of 48 (508 KB).
• Syntax colours in editors. Request bodies, scripts, examples, gRPC messages, GraphQL variables and AI-written tests are coloured as JSON or JavaScript.
• Updates that finish themselves. Dispatch now checks for updates every time it starts and every 4 hours while it's open. A banner stays until you install or dismiss it, shows download progress, and restarts the app when it's done. Settings has a Check for updates button and shows the version you're on.
• New look. The accent colour is now mint, matching the new landing page.
• More Postman scripts run unchanged. Number methods from Postman's original sandbox (round, ceil, floor, pad and others, from Sugar.js) now work, so shared scripts that call things like (n).round() no longer fail.

macOS only. Windows and Linux stay on v0.5.0 for now. Mac users on 0.5.0 or 0.6.0 get this update in the app. On those versions the prompt comes at most once a day when the app starts, and after Update & restart you need to quit and reopen Dispatch yourself. From 0.6.1 on, the restart happens automatically.

The app is unsigned: on first launch, right-click → Open.
