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-4 (param-impl SOURCE, ambiguous) — because a parameterised-impl wrapped
// SOURCE type is now registered SOURCE-AWARE (the source `*Box` flows through
// `resolveRegistrationSigTypeInSource` → `resolveCompound` → `resolveNominalLeaf`),
// a genuinely ambiguous same-name element poisons LOUDLY at registration instead of
// silently selecting a global `findByName` last-wins author. `main` flat-imports two
// `Box` authors and declares none itself, so `impl Into(Marker) for *Box` cannot
// pick a `Box` and the build exits 1.
//
// Fail-before (pre-E6BR-4): the source `*Box` fell to the no-author
// `type_bridge.resolveTemplateSignatureType` wrapper (global last-wins, no
// diagnostic), so the collision was registered silently.
