eldritch horrorsandjade b0d7a81613 fix tooling after include reorganization
clangd broke because it can't look through symlinks. compile_commands
manipulation does not fix it, clangd configuration does not fix it, a
vfs overlay does not fix it, and while a combination of those can fix
it with a bind mount in place that's just too cursed to even consider

clangd bug: https://github.com/llvm/llvm-project/issues/116877

substring

s

Return the substring of s from character position start (zero-based) up to but not including start + len. If start is greater than the length of the string, an empty string is returned, and if start + len lies beyond the end of the string, only the substring up to the end of the string is returned. start must be non-negative. For example,

builtins.substring 0 3 "nixos"

evaluates to "nix".
