[Guitar Tools] Add audio device selection for external audio interfaces

[4fun50]

Description

This PR adds the ability to select a preferred audio input device for the Guitar Tools tuner, which is particularly useful for guitarists using external audio interfaces or sound cards to connect their instruments.

Changes

• Added new command "List Audio Devices" to view and select available audio input devices
• Implemented LocalStorage to persist the selected audio device across sessions
• Modified tuner to use the selected device instead of always defaulting to the built-in microphone
• Improved device name detection regex to support all device naming conventions (including names starting with lowercase letters or numbers)
• Updated README.md with usage instructions for external audio interfaces
• Updated CHANGELOG.md with all new features

How to use

1. Run "List Audio Devices" command
2. Select your preferred audio input device (e.g., audio interface)
3. The tuner will now use the selected device automatically

Testing

Tested successfully with:

• iRig HD 2 audio interface
• Built-in MacBook microphone
• External USB microphone

Greptile Overview

Greptile Summary

This PR adds audio device selection functionality to the Guitar Tools extension, allowing users to choose their preferred audio input device (particularly useful for external audio interfaces).

Key changes:

• New "List Audio Devices" command that parses system_profiler output to display available audio input devices
• LocalStorage-based persistence for selected device preference
• Modified tuner to use selected device via Sox's CoreAudio interface

Critical issue found:

• Shell injection vulnerability in note.utils.ts line 67 where device name is interpolated into shell command without proper escaping

Minor issues:

• CHANGELOG has duplicate headers and inconsistent dates
• React key using array index instead of unique identifier

Confidence Score: 2/5

• This PR has a critical security vulnerability that must be fixed before merging
• Score reflects the shell injection vulnerability in note.utils.ts where the audio device name is inserted into a shell command without proper escaping. This could allow command injection if a device name contains shell metacharacters. The rest of the implementation is sound.
• Pay critical attention to extensions/guitar-tools/src/utils/note.utils.ts - the shell command construction needs proper escaping
