Greptile Overview

Greptile Summary

This PR adds new Cap deeplink actions for recording control (pause/resume/toggle) and device management (set/switch camera/mic) in apps/desktop/src-tauri/src/deeplink_actions.rs, and introduces a new Raycast extension under extensions/raycast/ with seven no-view commands that invoke those deeplinks and provide HUD feedback.

Main concern: the deeplink URL parsing/validation logic in DeepLinkAction::try_from appears inverted, causing valid cap-desktop://action?... URLs to be treated as Invalid, which would prevent the Raycast commands (and any other deeplink client) from working at all.

Minor follow-ups include making the Raycast “Cap installed” check consistent across commands, and avoiding non-reproducible @latest usage in the extension’s publish script.

Confidence Score: 2/5

• Not safe to merge until deeplink parsing is fixed, since it likely breaks all deeplink-driven actions.
• Confidence is lowered by a likely logic error in DeepLinkAction::try_from that rejects valid cap-desktop://action URLs, which is core to the PR’s functionality. Other issues are smaller UX/reproducibility concerns.
• apps/desktop/src-tauri/src/deeplink_actions.rs
