Skill now covers full CLI usage (hermes setup, hermes skills, hermes
tools, hermes config, session management, etc.), config file reference,
and expanded gateway commands.
Agent context notes for STT failure now mention the hermes-agent-setup
skill is available to help users configure Hermes features.
When a user sends a voice message and STT isn't configured, the gateway
now sends a clear message directly to the user explaining how to set up
voice transcription, rather than relying on the agent to relay an
injected context note (which often gets misinterpreted).
Also adds a hermes-agent-setup bundled skill covering STT/TTS setup,
tool configuration, dependency installation, and troubleshooting.
