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.

// Pure-sx fn-pointer cast: a function-pointer typed without `abi(.c)`
|
|
// keeps the default (sx) calling convention. Passing a >16-byte aggregate
|
|
// through that pointer must not get the C-ABI byval coercion — the sx-CC
|
|
// callee expects the struct as an SSA value, not as a `ptr byval(<T>)`.
|
|
//
|
|
// Pair with examples/86-abi-c-fnptr-large-aggregate.sx, which covers
|
|
// the opposite arm (fn-pointer typed `abi(.c)` does get byval).
