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.

// E6BR-2 / G8 (own-wins) — a protocol method-signature CONCRETE named return type
// resolves SOURCE-AWARE, pinned to the protocol's defining module. `main`
// flat-imports `dep.sx` (`Box { a }`) AND authors its OWN `Box { m }`; the
// protocol `Provider` returns `Box` and the impl builds main's `Box`. Dispatching
// `p.get()` must type the result as MAIN's `Box`, so `b.m` resolves.
//
// Fail-before (pre-E6BR-2): the method signature went through the no-author
// `type_bridge.resolveTemplateSignatureType` wrapper (global last-wins), so the
// return typed as dep's `Box { a }` and `b.m` was `field 'm' not found on type
// 'Box'`. Pass-after: source-aware → main's `Box`, exit 0.
