Add scripts/clj_timing_probe.py — a click CLI that runs the Clojure Mode A replay driver (math/dev/replay.clj) at increasing vote-count sizes, records wall-clock seconds + final-blob success per size, fits runtime ~ a + b*N^k (log-log least squares, a estimated from the smallest run as the fixed JVM-startup cost), and recommends the largest N that stays within a wall-clock budget. TDD: tests/replay_harness/test_timing_probe.py mocks the clojure subprocess for all unit tests (CSV truncation, schedule shape, fit recovery on synthetic power-law data, recommendation math, stdout line budget, CLI end-to-end) plus one real-subprocess integration test gated on `clojure` being on PATH and RUN_CLJ_INTEGRATION=1. commit-id:96c1f19e
