Resource Pack Overrides config field names extracted directly from the
mod's class files (default_packs + default_overrides confirmed via grep
on the .class strings). Config ships through defaultconfigs/ so it
seeds the player's local config on first run and respects later edits.
The 'default_position: TOP' override puts the ReCreated pack at the top
of the enabled-packs list so it takes precedence over the vanilla
ComputerCraft textures.
If the filename or schema turns out to be off when tested, it's a
one-line follow-up to fix.
The previous rule 'pack/overrides/' ignored the whole directory, which
made it impossible to re-include subpaths via ! exception (git's rule).
Narrow the ignore to 'pack/overrides/mods/' -- the only path that
Build-Tweaks.ps1 actually writes -- and drop the broken whitelist
block. Other subdirs under pack/overrides/ (defaultconfigs/, etc.) now
live in git like normal source.
Adds the Waystones override that 0.16.1 attempted (spawnInVillages =
DISABLED). Bumps to 0.16.3 so launcher caches re-sync.
