Master fixed the embed_spirv.py concurrency race independently and better
(tempfile.TemporaryDirectory cleans up on early-return error paths too), so the
rebase conflict was resolved in master's favour and our mkdtemp version
removed. This branch stays SPU-only.
Records the trap that invalidated the first Tomba 2 measurement: game.toml's
overlay_autocompile_cmd names a recompiler path, and when it is absent
autocompile fails every attempt, no shard is ever built, and the runtime
silently interprets everything. Tomba 2 expects a worktree-relative path the
documented build recipe does not produce; MMX6 hardcodes an absolute path into
the main repo that works only by luck of local layout. Check autocompile_status
before trusting any perf number from a fresh worktree.
