standalone: 64 m full-detail override, detailed round tunnels, optional mesh cache -- generation itself NOT faster

ClipRadius override 3 (64 m at 25 cm). Uncached full detail 20.3 s on 8 workers (512 tiles at
~51 ms serial each should be ~3-4 s: the in-stream inefficiency is unsolved); full clipmap 170.6 s.
The 1 s / 5 s targets were met only from an on-disk mesh cache (.vfmesh, not committed) of
already-generated tiles: a revisit speed-up, not generation speed. Round tunnels gained
deterministic multi-scale wall relief and lost the larger mouth wedges (1.54% of lattice signs
changed, mean 0.20 m). Hashes stable across runs and 1 vs 6 workers.

+# Preliminary launch logs
+
+Each linked stdout log is one executable child launch; its matching `.stderr.log` is empty. Every
+process was started by the restricted BelowNormal launcher or is a preserved historical baseline
+log. PIDs for the speed2/speed3 exploratory launches are listed in
+`..\final\REPORT.md`; the early baseline launch PIDs were not retained in the current transcript.
