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.

// Own-wins for ENUM-PAYLOAD type registration over a NAMESPACED import.
// Regression (issue 0132, broader class).
//
// `#import "modules/std.sx"` carries the stdlib `event.Event` struct — it is
// NAMESPACED (reachable only as `event.Event`), never flat-visible. This file
// ALSO authors its OWN `Event :: struct { code }`, used as the payload of the
// enum `Wrap`. The payload type name `Event` must resolve at REGISTRATION to
// THIS file's own `Event` (which has `code`), not the namespaced stdlib struct.
//
// Fail-before: `registerEnumDecl` built the tagged-union body through the
// stateless `type_bridge.buildEnumInfo`, whose flat `findByName` picked the
// wrong same-name author — `got`'s payload became the stdlib `Event`, so
// `e.code` errored "field 'code' not found on type 'Event'". Fixed by threading
// the visibility-aware resolver (`*Lowering` as the `resolveInner` hook) through
// `buildEnumInfo` / `buildUnionInfo`, matching what `registerStructDecl` already
// does for struct fields.
#import "modules/std.sx";
