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.

// An IMPORTED generic template's field that names a type the CALLER declared
// only as a BLOCK-LOCAL must NOT bind that caller-local type — a block-local is
// visible only within its OWN source. `lib.sx` defines
// `Bad :: struct($T) { x: T; y: LocalOnly; }`; `main` declares `LocalOnly` only
// inside its own body before instantiating `Bad(i32)`. The imported template's
// module cannot see a caller block-local, so `y: LocalOnly` is undeclared in the
// lib file.
//
// Before the fix the global `local_type_names` set was source-insensitive: the
// template's field resolution (run in the template's source context, E3
// attempt-4) consulted it, found the caller's `LocalOnly`, and silently compiled
// (printed a value, exit 0). `local_type_names` is now keyed by declaring source,
// so a cross-source block-local no longer leaks into another source's resolution.
//
// Expected: `error: unknown type 'LocalOnly'` pointing into lib.sx; exit 1.
// Regression (stdlib E3 attempt-5).
