aither-interop

Use Aither from Hermes Agent and other harnesses, in both directions. Add awskills as a Hermes skill tap, point Hermes at a local Aither gateway over MCP with awnode mcp-config --format hermes, install a Hermes or agentskills.io skill into adk with adk skills install hermes:<owner>/<repo>/<skill>, and call another agent over A2A with adk mesh ls / adk invoke. Includes the trust boundary for third-party packs and the two places each side stores skills.
