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 raw value binding whose spelling shadows a builtin INTEGER type name
// (`` `i8 ``) used as an array DIMENSION through one of its fields. Field
// access on a raw value is an ORDINARY runtime field read, so `` `i8.max `` is
// a runtime value — NOT the builtin `i8.max` (= 127) and NOT a compile-time
// constant. An array dimension demands a compile-time integer constant, so the
// dimension is rejected with the same diagnostic a plainly-named runtime field
// read (`b.max`) earns — the backtick spelling changes nothing.
//
// Sibling (integer) half of the F0.11-7 fix: the compile-time INTEGER evaluator
// (`evalConstIntExpr`) misclassified a raw value-shadow receiver as the builtin
// `<IntType>.min`/`.max` accessor, silently folding 127 and fabricating a
// 127-element array. The `is_raw` guard now defers it to an ordinary field
// read, so it surfaces as a non-constant dimension instead of a silent wrong
// length.
//
// Negative companion to 0169 (the FLOAT-field narrowing half, exit 0).
//
// Regression (issue 0095 / F0.11-7).
