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, own-wins) — a parameterised-impl SOURCE type under a
// wrapper (`impl Into(Marker) for *Box`) registers SOURCE-AWARE, pinned to the
// impl's defining module (main), and the `xx` lookup at the use site mangles to the
// SAME author, so the conversion is found and runs. `main` authors its OWN
// `Box { m }` and flat-imports `dep.sx` (`Box { a }`); the `*Box` source binds
// main's `Box`, so `convert`'s `self.m` resolves and `xx @b` selects this impl.
//
// This locks the route-all registration path for the param-impl-source surface:
// the source `*Box` flows through `resolveRegistrationSigTypeInSource` →
// `resolveCompound` → `resolveNominalLeaf` (own-wins), never the no-author leaf.
// The param_impl_map key is name-based (`Into\0Marker\0*Box`), so registration and
// `tryUserConversion` agree by construction.
