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 type construction from a List grown at compile time: assemble the
|
|
// variant set in a `List(EnumVariant)` via `.append` (which allocates + grows
|
|
// its backing through the comptime `context.allocator`), then mint an enum from
|
|
// the grown backing sliced to its length — `vs.items[0..vs.len]`. The comptime
|
|
// VM evaluates the List growth, the slice, and `define`/`declare` end-to-end.
|
|
//
|
|
// A `[*]T` many-pointer (the List's bare `items` field) carries no length, so it
|
|
// must be sliced with `[0..len]` to form a `[]T`; passing `vs.items` bare is a
|
|
// rejected coercion (see the diagnostic example for that path).
|
|
//
|
|
// Regression (issue 0141): the List-grown form used to segfault in the comptime
|
|
// VM's slice decoder.
