feat(shell): remove cmd, add ksh/tcsh/csh support, shell-first exposure

- Remove 'cmd' from default TOOLS list - only detected shell exposed
- Add KshTool, TcshTool, CshTool for enterprise Unix shells
- Fallback to ShellTool (smart auto-detect) if shell detection fails
- Support ksh93, pdksh, mksh as aliases for ksh
- Bump hanzo-tools-shell to 0.6.1, hanzo-mcp to 0.10.37

+- Native macOS AVFoundation capture (fastest)
+- FFmpeg fallback for cross-platform
+- Real-time frame streaming for AI analysis
+- Multiple output formats (H264, WebM, GIF)
+
+Performance characteristics:
+- Native capture: 60fps at 1080p with <10ms latency
+- Frame streaming: Individual frames for real-time AI vision
+- Background recording with async control
+
+Claude Vision Optimization:
+- Frames resized to 768px (optimal for Claude vision)
+- Max 10 frames per batch to fit context limits
+- JPEG compression (quality 85) for smaller payloads
+- Smart frame selection (detect changes, skip duplicates)
+- Estimated 100-200KB per frame after optimization

+Actions:
+- start: Start screen recording
+  - output: Output file path (optional, defaults to temp)
+  - fps: Frames per second (default 30)
+  - quality: Recording quality (low, medium, high)
+  - region: [x, y, width, height] to record specific area
+
+- stop: Stop recording and return file path
+
+- status: Get current recording status
+
+- pause/resume: Pause or resume recording
+
+- frame: Capture single frame (fastest method)
+  - Returns base64 PNG
+  - Use for real-time AI vision
+
+- frames: Capture multiple frames
+  - count: Number of frames (default 10)
+  - interval: Time between frames in ms (default 100)
+
+- frames_claude: RECOMMENDED - Claude-optimized frame capture
+  - Automatically resizes to 768px (optimal for Claude vision)
+  - JPEG compression (~100-200KB per frame)
+  - Max 10 frames to fit context limits
+  - Skips duplicate frames automatically
+  - count: Number of frames (max 10)
+  - interval: Time between frames in ms (default 100)
+
+- stream: Start frame streaming
+  - fps: Target frames per second (default 10)
+  - Returns: stream_id for polling
+
+- save: Save recording to specific path
+  - output: Target file path
+  - format: Output format (mp4, webm, mov)
+
+- gif: Convert recording to GIF
+  - output: Output path
+  - fps: GIF frame rate (default 10)
+  - width: Scale width (default 640)
+
+Examples:
+    video(action="start", fps=30, quality="high")
+    video(action="frame")  # Get single frame for AI analysis
+    video(action="frames", count=5, interval=200)  # 5 frames, 200ms apart
+    video(action="frames_claude", count=10, interval=500)  # Claude-optimized: 10 frames over 5s
+    video(action="stop")
+    video(action="gif", output="demo.gif")
+
+Claude Vision Best Practices:
+    - Use frames_claude for video analysis (auto-optimized)
+    - 10 frames max per request (~1-2MB total)
+    - 500-1000ms intervals capture meaningful changes
+    - Frames are 768px JPEG for fast processing
