v0.3: plan, commit, transit, arrive
The journey core is complete: pick a star, commit, watch both clocks run, and arrive. Once you commit, there is no going back.
What's new
- Commit: hold for 1.5 s. After that the simulation refuses every cancel, and says so.
- Transit and arrival: the phase, both clocks, the distance flown and the energy radiated, live, until you arrive.
- Deterministic replay: a 10,000-tick session replays byte for byte on the AILANG VM and the interpreter.
- v0.3.1 opens straight onto the galaxy map; v0.3.2 adds trackpad zoom and Retina scaling.

The interior of the ship, and a journey you live through on board, are the next milestone (M4).
