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.

// ASM stream — symbol operand (`"s"`) on x86_64 (cross-arch sibling of the
|
|
// aarch64 1656). A DIRECT `call` to an `export`ed sx function by symbol, written
|
|
// with the SAME portable `%[fn]` as the aarch64 example — the compiler injects
|
|
// the `:c` operand modifier for symbol operands, so the symbol prints bare on
|
|
// every target (x86 would otherwise render `$cb`, a bad call target). The
|
|
// backend emits the platform-mangled name (`call cb` on Linux). x86-pinned;
|
|
// ir-only here, runs on x86_64-linux. Round trip: sx → asm → call cb → sx → 42.
