feat(deeplink): add recording controls and raycast extension #1540

Extends the DeepLinkAction enum with PauseRecording, ResumeRecording,
TogglePauseRecording, SwitchMicrophone, and SwitchCamera variants.
Adds a companion Raycast extension with two commands: cap-control
(recording lifecycle) and switch-device (mic/camera switcher).

All Rust code uses the ? operator for error propagation (no .unwrap).
API key in Raycast is stored via LocalStorage, never hard-coded.

Closes #1540
```

## Git Commands to Submit the PR

### Step 1 — Fork & clone (if not already done)

```bash
# Fork the repo on GitHub first, then:
git clone https://github.com/<YOUR-USERNAME>/Cap.git
cd Cap
git remote add upstream https://github.com/CapSoftware/Cap.git
```

### Step 2 — Create a feature branch

```bash
git checkout -b feat/deeplink-raycast-1540
```

### Step 3 — Copy the generated files

```bash
# Rust change
cp path/to/cap-bounty-1540/apps/desktop/src-tauri/src/deeplink_actions.rs \
   apps/desktop/src-tauri/src/deeplink_actions.rs

# Raycast extension
cp -r path/to/cap-bounty-1540/extensions/raycast extensions/raycast
```

### Step 4 — Stage and commit

```bash
git add apps/desktop/src-tauri/src/deeplink_actions.rs
git add extensions/raycast/
git commit -m "feat(deeplink): add recording controls and raycast extension #1540

+# Cap — Raycast Extension
+<!-- Fix for Issue #1540 - Deep Links & Raycast Support -->
+
+Control your [Cap](https://cap.so) screen recording sessions directly from Raycast — no mouse required.
+
+## Commands
+
+| Command | Description |
+|---|---|
+| **Cap: Recording Controls** | Start, stop, pause, resume, or toggle your recording session |
+| **Cap: Switch Input Device** | Switch the active microphone or camera |
+
+## Requirements
+
+- **Cap for macOS** installed from [cap.so](https://cap.so)
+- A **Cap API key** (only required for the device switcher — find it in Cap Settings → Developer)
+
+## How It Works
+
+Both commands build a `cap-desktop://action?value=<JSON>` deep link and call `open()` to hand off control to the Cap desktop app. Cap handles all state transitions; this extension stays stateless.
+
+### URL Schema
+
+```
+cap-desktop://action?value=<URL-encoded JSON>
+```
+
+| Action | JSON |
+|---|---|
+| Start Recording | `{"type":"startRecording","captureMode":{"screen":"Built-in Display"},...}` |
+| Stop Recording | `{"type":"stopRecording"}` |
+| Pause Recording | `{"type":"pauseRecording"}` |
+| Resume Recording | `{"type":"resumeRecording"}` |
+| Toggle Pause | `{"type":"togglePauseRecording"}` |
+| Switch Microphone | `{"type":"switchMicrophone","label":"MacBook Pro Microphone"}` |
+| Switch Camera | `{"type":"switchCamera","id":"<deviceId>"}` |
+| Disable Microphone | `{"type":"switchMicrophone","label":null}` |
+| Disable Camera | `{"type":"switchCamera","id":null}` |
+
+## Setup
+
+### Cap: Recording Controls
+No setup required. Just invoke the command and select an action.
+
+### Cap: Switch Input Device
+1. Open the command in Raycast.
+2. On first use you'll be prompted to enter your Cap API key.
+3. The key is stored in Raycast's encrypted local storage — never sent anywhere except the Cap API.
+4. Select a microphone or camera to switch. Cap will activate the chosen device immediately.
+
+## Security
+
+- API keys are stored in **Raycast's `LocalStorage`** (encrypted, sandboxed per extension).
+- No credentials are hard-coded or logged.
+- Deep links only communicate with the locally running Cap app.
+
+## Development
+
+```bash
+cd extensions/raycast
+npm install
+npm run dev     # Hot-reload development mode
+npm run build   # Production build
+npm run lint    # ESLint check
+```
