Add hot-corners extension

[JoaoGFdev]

Description

Control macOS hot corners from Raycast: save named layouts, switch between them, or turn all corners off and back on. Changes use the same settings as System Settings and apply the Dock preferences (the Dock is restarted so updates take effect).

Commands

Command	What it does
Save Hot Corners Preset	Save your current hot corner setup (each corner’s action and modifier) under a name.
List Hot Corners Presets	Open your presets, search, apply one, reorder, or delete. Applying updates the system and restarts the Dock.
Toggle Hot Corners	If corners are on: turn all corners off and remember the previous setup. If they’re off: restore that setup. The command’s subtitle in Raycast shows Enabled or Disabled to match the current state.

How to use

1. Save a few presets (e.g. “Work”, “Gaming”) after configuring corners in System Settings, or from whatever layout you want stored.
2. List presets when you want to switch layouts without opening System Settings.
3. Toggle when you want everything off (or back) in one action—useful for screen sharing or focus.

Greptile Summary

This PR introduces a new hot-corners extension for macOS that lets users save named presets of their hot-corner configuration, apply them, and toggle all corners off/on — all via defaults write on com.apple.dock and a Dock restart.

• @raycast/utils is declared as a dependency in package.json but is never imported in any source file — it should be removed.

Confidence Score: 3/5

Safe to merge after removing the unused @raycast/utils dependency; all other findings are minor style issues.

One P1 finding (unused declared dependency violating the project rule) pulls the ceiling to 4/5; combined with two P2s and the P1 being straightforward to fix, a score of 3 reflects that the fix is required before merge.

extensions/hot-corners/package.json — remove the unused @raycast/utils entry from dependencies.

Important Files Changed

Filename	Overview
extensions/hot-corners/package.json	Extension manifest is well-formed, but @raycast/utils is listed as a dependency without being imported anywhere in the source — this unused dependency should be removed.
extensions/hot-corners/src/lib/hot-corners.ts	Core library: reads/writes macOS Dock defaults via execFileSync and manages presets as JSON on disk. Logic is solid — input validation, safe defaults, and disk I/O are all handled carefully.
extensions/hot-corners/src/toggle-hot-corners.tsx	Toggle command logic is correct; minor concern that the try/finally lacks a catch, so errors from applyHotCornerSettings won't surface a user-friendly message.
extensions/hot-corners/src/list-presets.tsx	Preset list UI is clean and well-structured; minor inconsistency in action title casing ("Move up" vs "Move Down").
extensions/hot-corners/src/save-preset.tsx	Save-preset form is straightforward and correctly validates the name field before persisting.

Comment:
**Unused `@raycast/utils` dependency**

`@raycast/utils` is declared as a dependency but is never imported in any source file under `src/`. This adds unnecessary weight to the bundle and violates the project rule requiring every listed dependency to be used. Remove it from `dependencies`, or import the package if it is actually needed.

```suggestion
    "@raycast/api": "^1.104.13"
```

**Rule Used:** What: Every dependency listed in package.json must... ([source](https://app.greptile.com/review/custom-context?memory=bffc60eb-f9f2-4219-b804-76e29e267d43))

Comment:
**Missing error handler in `try/finally`**

The outer `try` block has only a `finally` — no `catch`. If `applyHotCornerSettings` (or any other synchronous call) throws, the error propagates out of the exported function without any user-visible feedback. The `finally` still runs `syncToggleCommandSubtitle`, but the failure itself is never surfaced through a `showToast` or `showHUD`. Wrapping the body in a `try/catch/finally` ensures users see a meaningful error message rather than a silent failure or a generic Raycast error dialog.

Comment:
**Action title casing inconsistency**

`"Move up"` uses sentence case while the sibling `"Move Down"` uses title case. Raycast action titles should consistently use title case.

```suggestion
                    title="Move Up"
```
