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

hasContext
s

Return true if string s has a non-empty context. The context can be obtained with getContext.

Example

Many operations require a string context to be empty because they are intended only to work with "regular" strings, and also to help users avoid unintentionally losing track of string context elements. builtins.hasContext can help create better domain-specific errors in those case.

if builtins.hasContext name
then throw "package name cannot contain string context"
else { ${name} = meta; }
