refactor: mover runtime Go de agents/ a devagents/

agents/ ahora solo contiene carpetas de agentes (config, reglas, prompts).
El runtime (Agent, Robot, Runner, registry, handler, commands, llm, memory)
vive en devagents/ como package devagents.

Cambios:
- git mv agents/*.go → devagents/*.go
- package agents → package devagents en todos los archivos movidos
- Actualizar imports en agents/*/agent.go, cmd/launcher/, dev-scripts/
- Actualizar docs: CLAUDE.md, rules/, docs/e2ee.md, issues pendientes

Build y tests pasan sin errores.
