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.

// Phase 1.3 — the closure env-buffer heap-copy in `lowerLambda` must
|
|
// dispatch through `context.allocator`, not `.heap_alloc` directly.
|
|
// So when a `push Context.{ allocator = tracer }` block is active, a
|
|
// capturing closure created inside it MUST allocate its env through
|
|
// the tracker.
|
|
//
|
|
// Mirrors the shape of `130-xx-value-routes-through-context-allocator.sx`
|
|
// for the protocol-erasure heap path — same Tracer, same install via
|
|
// `push Context`, same `Tracer.count = 1` assertion. Different
|
|
// allocation site (closure env vs xx-value heap copy).
