v1.7.49

v1.7.49 — .nf goto stop landing overhaul

• Staged descent — scans 32m below and stages the dive (30° when high, 12° on final, flare under 10m) instead of a fixed shallow 15°. You get down fast; "stop" no longer drifts hundreds of blocks.
• Wall-impact guard — the landing now runs the same 5-ray forward scan as cruise; a hillside ahead means climb-and-skim first. Elytra kinetic damage was previously unguarded during landing.
• Lava guard (nether) — a fluids vs blocks-only ray pair detects a lava surface below; the autopilot holds altitude and glides to solid ground instead of flaring into the lake.
• Release cap 10s → 30s — no more mid-air control release when descending from cruise altitude over deep terrain.
• Actionbar shows height-above-ground plus obstacle/lava notes.
