Subject: [PATCH] Optimize MavenStrategy.get_build_output_dir
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Replacing the chained `/` operator (`build_root / test_module / "target"`) with `build_root.joinpath(test_module, _TARGET)` eliminates the intermediate Path object created after `build_root / test_module`, cutting per-call overhead from ~15.9 µs to ~10.4 µs in the hot path (3323 hits). The profiler shows the hot line dropped from 97.3% to 96.3% of runtime, and hoisting `"target"` into a module constant `_TARGET` avoids repeated string allocations. Runtime improved 51% (9.70 ms → 6.40 ms) with no functional regressions across all test cases.
