b368912c78 nav, physics: Recast's and Detour's memory counted (nav_heap_bytes / _peak / _allocs, a counted allocator registered at load, tile bytes staged from it); package tests that crossing the map and back holds the native bytes
The user's walk showed the footprint rising outside the Ludic heap. Jolt's bytes were already counted;
the navmesh's were not, so nothing could see them. Now:
- ludic.nav nav_heap_test: fifty crossings of a four-tile map by the resident index hold the tiles in and
  the native bytes to the first crossing's; a thousand crowd walkers in and out grow nothing; a reset
  gives back every byte the mesh took.
- ludic.physics cross_heap_test: a 1 km map of 64 m chunks kept to a ring round a player crossing
  corner to corner and back, each chunk a heightfield, twelve owned posts and six owned scaled hulls
  as the game makes them: six more crossings hold the bodies, the shapes and Jolt's bytes and peak
  exactly. (A post made as an offset of a cylinder, with only the offset owned, leaked the cylinder
  every time: the game's solid_pillar owns its cylinder directly.)

lib/macos-arm64 rebuilt; lib/windows-x64 needs native/build.sh run on the PC for the new exports.

e807fd556c ludic.nav (23.5b): a baked mesh resident by chunk
nav_load_index indexes a saved mesh's tiles (cell, offset, size, ref) from their headers and keeps the file open, with no tile in. nav_tiles_keep reads in the tiles within rin of any player and removes those past rout of all; the file is read through Ludic's pack-aware file_open. The file format is unchanged. tiles_test: tiles come and go with the point, a path works across the seams once they are in, and a reset closes all. Measured on the baked maps (the 900 / 1100 m ring round the start): Maroon 617 of 1807 tiles in, 8.9 MB instead of about 27 MB for a person and 5.4 MB of about 14 for a large walker; Lamar 391 of 1147. Both libraries are rebuilt; nav 17/17 on the Mac and the PC, DLL KERNEL32 only.
