Improve runtime stutter handling and ground clutter performance

- reduce per-tile ground clutter generation pressure and enforce tighter caps to avoid spikes

- remove expensive detail dedupe scans from the hot render path

- add progressive/lazy clutter updates around player movement to smooth frame pacing

- lower noisy runtime INFO logging to DEBUG/throttled paths

- keep terrain/game screen updates responsive while preserving existing behavior
