agra 66bdc70bf1 test: group examples into per-category folders
Move examples/*.sx and their expected/ snapshots into per-category
subfolders (examples/<category>/...). Folder = leading filename token,
with ffi-objc/ffi-jni kept whole; filenames are unchanged. The corpus
runner and LSP sweep now discover each category's expected/ dir, while
issues/ stays flat. Example 1058's repo-root-relative companion import
is made file-relative. Path strings embedded in 164 snapshots were
regenerated (path-only changes). Test-layout docs in CLAUDE.md updated.

// An ARRAY argument at a generic slice param (`xs: []$T`) binds T from
// the array's element type — the same array→slice promotion concrete
// slice params perform — for scalar and struct elements, with the
// return-position `T` resolving to the element type. The slice
// spelling keeps working unchanged.
//
// Regression (issue 0126): the binding extractor only accepted slice
// args, so `first(a)` left T unbound and the monomorphized body
// reached LLVM emission with the `.unresolved` sentinel (panic).
