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.

// Chained runtime-class method dispatch: `Cls.static().instance(...)`
// resolves the inner call's return type so the outer dispatch's
// receiver type is known. Pre-fix this collapsed to i64 in
// `inferExprType`, the runtime_class_map lookup missed, and lowering
// emitted `error: unresolved 'init'` (or 'initWithWindowScene' etc.)
// — see issues/0043 for the chess uikit.sx C4 migration that hit it.
//
// Two return-type shapes covered: explicit `*ClassName` (alloc here)
// and `*Self` (init). Both must propagate through the chain so the
// next `.method(...)` finds the runtime-class declaration.
