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.

// Erase two DISTINCT comptime-pack elements to protocol locals — each gets
|
|
// its own heap copy and resolves to its OWN concrete type's method (IntCell.get
|
|
// vs Doubler.get), proving the per-element erasure picks the right vtable.
|
|
//
|
|
// Regression (issue 0135): single-element `xx pack[i]` erasure to a protocol
|
|
// scalar was unsupported (the bare pack lowered as a value and errored).
