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.

// Comptime TUPLE metaprogramming — `define` constructs a tuple and `type_info`
|
|
// reflects one, completing the reflect/construct triad (enum 0619, struct 0622,
|
|
// tuple here). Tuples are POSITIONAL, so `TupleInfo` is just a `[]Type` (no field
|
|
// names). Two paths:
|
|
// 1. Programmatic build: `define(declare("Pair"), .tuple(.{ elements = … }))`.
|
|
// 2. Round-trip: `define(declare("TripleCopy"), type_info((i64, bool, f64)))`
|
|
// reflects a source tuple type INTO a `.tuple(TupleInfo)` value and
|
|
// reconstructs it — no literal element list.
