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.

// Regression test for issue-0025 path A.

//
|
|
// sx functions declared with `abi(.c)` that take a composite > 16 bytes
|
|
// by value must marshal the arg through `ptr byval(<T>)` per AAPCS64 / SysV
|
|
// AArch64: the caller copies the struct to an alloca, passes the alloca
|
|
// pointer with a `byval(<T>)` attribute, and the callee's entry block loads
|
|
// the struct back from the pointer.
|
|
//
|
|
// Before the fix, abiCoerceParamType returned the raw LLVM struct type for
|
|
// >16-byte composites (TODO at src/ir/emit_llvm.zig:2793), so the C ABI
|
|
// promise was silently violated whenever sx-emitted C-callable code
|
|
// interoperated with a real C caller.
