Big news: There's now a solution available to flash ESPHome on the original microcontroller that comes with the Star Projector which even doesn't require to open the device (!). Everything works via direct WiFi connection between your computer and the Star Projector (the projector provides a WiFi access point). So no more replacement of the original microcontroller requiring soldering, this is the most convenient jailbreak one can think of.
I found only two minor issues at the moment (minor because they can both be addressed via Home Assistant automations for instance):
With unchanged settings after turning on the projector it turns off itself automatically after about one hour. I just started to investigate this by e.g. testing if it makes a difference if I leave the motor off.
When you turn the device on using the main switch it doesn't remember the last state of lights/laser/motor when it was on before.
I immediately bought a second device after I had successfully flashed the first one. Both devices show the same behaviour described above.
This is how this jailbreak miracle looks like in HA:
