- Split Analyzer.analyze/1 into compute_state/1 (slow, scans all BEAMs) and a fast filter step. analyze/1 now accepts :precomputed_state opt. - Mix.Tasks.Compile.Unused.run/1 picks up precomputed state from process dict :mix_unused_extra_analyze_opts when present (test escape hatch). - AnalyzerTest setup_all computes state once; exclude tests pass it through analyze/1, dropping per-test cost from ~700ms to <1ms. - UnusedTest setup_all does the same — the consolidated severity-args test drops from 3.4s to ~5ms. - Trim further sleeps in HistoricalLoadingTest (100->30ms) and MovementTest (50->20ms, receive timeouts 100->30ms). Total suite: 40.6s -> 37.7s; 2488 tests, 0 failures.
