agent
fc644ecd6e
Reemplaza el scaffold del echobot por la plataforma completa de bots traida desde ~/DataProyects/Github/agents_and_robots tras la operacion Matrix-out: los bots ya no hablan por Matrix sino por el bus unibus (modelo todo-rooms + E2E via shell/transportunibus sobre github.com/enmanuel/unibus/pkg/client). - go.mod: replace de unibus -> ../unibus y de fn-registry -> ../../../.. (paths relativos reajustados a la nueva ubicacion dentro de fn_registry). - app.md: bump a 0.2.0, descripcion + arquitectura + comandos + gotchas reales. - modulo Go conservado como github.com/enmanuel/agents (sin reescribir imports). agents_and_robots queda archivado como museo de la era Matrix.
