Add a lived-in layer: settlements in generated systems
The galaxy was settled long before the player arrives. Systems now
host colonies on habitable worlds, mining stations over resource
worlds, cloud bases riding gas giants, stations adrift in open
space, and beacons — or report "charted · unclaimed" when empty.
- data/settlements.json: the shared kind vocabulary (label, theme,
population range, anchor type); add a kind = JSON + naming pool.
- Per-archetype rates in data/systems.json (chance + required
planet class) and a core→rim density gradient in data/galaxy.json
(falloff/floor), keyed off each record's new rNorm.
- Draws stay in a stable order on the system's own Rng stream, so
lazy and eager generation still produce identical content.
- Every settlement keeps owner: null, a reserved seam for the
factions/pirates that will claim them later.
- NameGenerator.station() names from anchor + kind ("Kest Skyspire").
- SystemReport.js is a pure, testable formatter (dossier lines,
"charted · unclaimed" for empty); GameScene's HUD renders it and
Node tests cover structure, mix, gradient, naming, lazy === eager.

the wilder rim (`data/galaxy.json`). Each settlement has a name,

population, and an `owner` seam reserved for the factions/pirates to come.

in infinite, unbounded space (system boundaries/jumps come next)
