agra 66bdc70bf1 test: group examples into per-category folders
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.

// Call-site default-argument expansion (`appendDefaultArgs` / `expandCallDefaults`
// in lowerCall). A call that omits a trailing parameter with a default value
// has the default expression spliced in at the call site; an explicit argument
// overrides it. Two trailing defaults cover the "fill all remaining" path.
// Path-free IR (literal defaults) so the `.ir` snapshot is location-stable.
