⏱️ shelltime track performance

✅ No significant change in shelltime track latency

Comparing main @ e028b58 → #321 @ 4536aae. Each scenario execs the binary the way the shell hooks do; values are the median of 10 interleaved rounds. Lower is better.

_{Δ compares medians; ~ means no significant difference (Mann-Whitney U, p ≥ 0.05). A scenario is flagged when it is more than 10% and more than 250µs slower with p < 0.05. Startup/floor runs true, not shelltime: it is an A/A check of runner noise. Runner: linux/amd64, AMD EPYC. go1.27.1, 10 rounds × 100 execs per scenario and binary.}
