The app used to always generate a world straight from planet.cfg on launch
and F5 always overwrote a single fixed planet.save. Now it opens on a
full-screen Main Menu (Home / Settings / Load World) so every PlanetConfig
field, the seed, starting a new world, and browsing saves are all reachable
without hand-editing planet.cfg, and saves are timestamped so nothing is
silently overwritten. A toolbar button reopens the menu later without
disturbing a running world.
The settings editor is generic (no per-field UI code): configFieldTable()
reuses the existing CONFIG_FIELDS X-macro to build a runtime field table,
grouped into 25 categories via an explicit name->category lookup (a
"first field of each section" boundary scan was tried first and is wrong,
since CONFIG_FIELDS emits all doubles, then all ints, then the seed --
not struct declaration order, so most categories aren't contiguous in that
order). Save v25 adds the viewer's colour-mode/overlay state, kept out of
Planet::writeState/readState's signature so it touches none of the
existing headless tests.
