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.

// A closure literal whose body `raise`s but is annotated non-failable (or has
|
|
// no `!` in its return) gets a LAMBDA-SPECIFIC diagnostic telling the user to
|
|
// declare the failable return explicitly (ERR E5.1 sub-feature 1). This is the
|
|
// closure analog of the top-level "raise is only valid inside a failable
|
|
// function" error — failability is never inferred for a lambda, it must be
|
|
// declared, so a raising lambda with no `!` is a hard error pointing at the fix.
