Cursor Agent 4100e12b20 perf: speed up no-op builds (resolve base once, cache interpreter detection) ... A no-op build's ~2-3s was almost all registry I/O: - the base index was fetched 3x (BasePlatforms + remote.Image per platform) - the base's top layer was downloaded once per platform every build to read /etc/apko.json for interpreter detection (Chainguard has no PYTHON_VERSION) Changes: - build.BaseSet resolves the base reference once and serves per-platform child images memoized (index fetched once; verified by TestBaseSet) - cache the detected interpreter version by base digest in a default per-user metadata cache (cache.GetText/PutText), so repeat builds skip the apko layer download - lazy wheel-cache dir creation; wheelhouse.Resolve defaults to the per-user cache dir Tests: TestBaseSet (index fetched once + per-platform memoized), TestCachedInterpreter (write + cache-hit short-circuit), cache text round-trip.
