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.

// Nested comptime call + return — a comptime fn (`$x: i32`) whose
// body contains BOTH a nested comptime call (`print`) AND a
// `return X;` statement must lower cleanly. The wrapper fn built
// by `createComptimeFunction` saves/restores `inline_return_target`
// so it doesn't inherit a slot belonging to the OUTER caller's
// basic block. Pre-fix: interp executed the wrapper with a
// stale-frame inline-return slot and tripped a null-pointer store
// at `storeAtRawPtr`.
//
// Repro: comptime fn (`$x: i32`) whose body has BOTH a nested
// comptime call (`print`) AND a `return X;` statement. Pre-fix:
// interp panics. Post-fix: prints "inside" then "n=42".
//
// The pack-fn variant of the same bug (filed in the original
// issue as face 2) was fixed earlier when step-2b moved pack-fn
// calls off the inline path into the mono path. Plain comptime
// fns stay on the inline path; their fix is the
// `createComptimeFunction` state save/restore.
