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.

// ASM stream — read-write (`+`) place output on x86_64 (cross-arch sibling of
// the aarch64 1650). `incq %[v]` reads the operand register, increments it, and
// the result is stored back through the place. Locks the x86 lowering of `+`:
// an output `=r` plus a tied input (`=r,0`) seeded with the place's value.
// x86-pinned via `.build`: ir-only here (the `.ir` is the assertion), runs
// natively on x86_64-linux (main returns 0 on success, 1 if the asm misbehaved).
bump :: () -> i64 {
x : i64 = 41;
asm volatile { "incq %[v]", [v] "+r" -> @x };
return x; // 42
}
main :: () -> i64 { if bump() != 42 { return 1; } return 0; }
