chore: avance acumulado de sesiones previas (reorg dev/issues + ajustes)

Reorganizacion de dev/issues en subcarpetas (completed/, cpp/, gamedev/,
kanban/, trading/, imagegen/, matrix/) y cambios acumulados en cmd/fn/pyrunner,
.claude/commands y settings. Trabajo de otro LLM/sesion, commiteado a peticion
del usuario para desbloquear el working tree. Excluido logs/ardour_mcp_server.log (ruido).
