Maybe I'm missing some crucial context, but why can't you preprogram the
agent with the optimal strategies for constructing an M-Brain and a
transceiver, and then copy yourself over as soon as that's done?

Are you assuming that we're only using the star's own energy output,
without generating additional energy with the extracted material? A kg of
material from the surface of a sun-like star has -2e11 J of gravitational
potential energy, but it can generate 3e14 J of energy through nuclear
fusion, so it seems quite feasible to disassemble a star quickly using its
own material as fusion fuel.
