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.

// M2.1(b) — class methods (no `*Self` first param) on a
|
|
// sx-defined `#objc_class`.
|
|
//
|
|
// The user declares a method without `self: *Self`. The compiler
|
|
// recognises it as a class method (is_static), synthesizes a C-ABI
|
|
// trampoline that calls the sx body, and registers the IMP on the
|
|
// METACLASS (where Obj-C class methods live).
|
|
//
|
|
// Verifies the runtime side:
|
|
// 1. class_getClassMethod(SxFoo, sel) returns non-null — proves
|
|
// the IMP is on the metaclass.
|
|
// 2. objc_msgSend(SxFoo, sel) invokes the IMP and returns the
|
|
// sx body's result.
