Add claudio: macOS voice dictation using Anthropic

Repository: https://github.com/ayushkumar1808/claudio

A practical tool that lets you dictate prompts system-wide on macOS using Anthropic's Deepgram Nova 3 speech-to-text. Hold Space anywhere to start; release to commit. No extra API keys needed. Good example of non-LLM Anthropic API usage.

Start by reviewing the Prompt-Engineering-Guide repository’s existing resource or tool listings, then inspect the linked claudio repository to verify its macOS voice-dictation and Anthropic details. Add claudio in the appropriate guide section with an accurate description and link; done means the resource is discoverable and its details match the project.
