Adds the slow real-time "Live World" mode (key W on a settled world) that runs the finished planet on an hours->weeks/months clock (liveTime/liveRate, [ / ] ramp the rate) with geology frozen. Everything new is a derived per-cell field flowed over the fixed grid. Day/night & seasons (PlanetLive.cpp): a raylib-free per-cell insolation field (computeInsolation) drives a moving day/night terminator (N) from time-of-day rotation + seasonal declination (axialTilt); a live seasonal temperature cycles the static summer/winter fields over the year (computeLiveSeason); a moving snow/sea-ice line tracks it. Day/night + snow are render overlays over any colour mode (3D + 2D). Save v8 stores the live clock. Sky & tides (PlanetOcean.cpp): 1-3 random moons (separate RNG, saved v9) orbit on the clock and, with the now small/distant sun, raise an equilibrium tide (computeTides -> sTide), shown as a tide-coloured coastline (T, buildCoastline + tideColor). Moons render with sun-lit phases, orbit rings and eclipses (solar shadow spot in the day/night overlay, lunar dimming). The 2D map is left-aligned; the freed space holds a Live-World "Sky & tides" panel (per-moon phase + a selected coastal tile's tidal phase). Ocean currents + climate feedback (PlanetOcean.cpp): computeOceanCurrents builds a per-ocean-cell tangent velocity from wind stress + Coriolis deflection + coast-following (gyres); computeClimate feeds warm (poleward) / cold (equatorward) currents back into sTemp as a bounded coastal anomaly (climateCurrentFactor) before seasons, so biomes shift. Rendered as warm/cold current arrows (O). Config: dayLengthHours/yearLengthDays/snowTemp/seaIceTemp/tideAmplitude/tideSunFactor/ climateCurrentFactor. Save header v7->v9 (version-gated; older saves load fine). Headless test_live.cpp + test_ocean.cpp; test_logic/test_biota still pass; GUI build clean. Docs updated.
