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.

// String `==`/`!=` as an operand of a short-circuit `and`/`or`.
|
|
//
|
|
// A string compare lowers to its own multi-block memcmp sub-CFG, so the
|
|
// operand finishes in a later basic block than the one the short-circuit
|
|
// started in. The `and`/`or` merge PHI must take that actual block as the
|
|
// incoming predecessor.
|
|
//
|
|
// Regression (issue 0078): combining string equality with `and`/`or` used to
|
|
// emit invalid LLVM (`PHI node entries do not match predecessors!`).
