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.

// A reserved/builtin type name is rejected as a binding name inside an `impl`
// block's method too — both as a parameter (`u8`) and as a local (`i2`). The
// impl method is reached through the exhaustive binding-name walk's
// `impl_block` arm (→ each method's `fn_decl`), so an `impl` method is no more
// exempt than a free function. Without the diagnostic the reserved local's
// `@i2` mis-lowers (a loaded aggregate passed by value to a `*Box` param →
// LLVM verifier abort).
//
// Regression (issue 0076, attempt-4 coverage). Expected: one error for the
// param and one for the local; exit 1.
