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.

// Backtick raw identifier in TYPE position (the universal model, issue 0089):
|
|
// `` `name `` is the LITERAL identifier `name` used as a type reference, never
|
|
// the builtin/reserved spelling. A reserved type spelling (`i2`, `u8`, …) can
|
|
// therefore both DECLARE a type (struct / enum / union / error-set / alias) and
|
|
// be REFERENCED as that type via the backtick — while a BARE `i2` in type
|
|
// position remains the signed-int type (see `add` below) and a bare reserved-
|
|
// name declaration still errors (see examples/1141). The backtick is required
|
|
// to declare or reference these names; it is never part of the name's text.
