Add a hands-on guide for using voice mode with Hermes, fix and expand the main voice-mode docs, surface /voice in messaging docs, and improve discoverability from the homepage and learning path.
Document the new global-only SOUL behavior, add a dedicated use guide, update personality/context/config docs, and fix docs language that still described cwd-local SOUL loading.
Expand the MCP feature docs with filtering and capability-aware registration details, add a practical 'Use MCP with Hermes' tutorial, add a config reference page, and wire the new docs into the sidebar and landing page.
