Nuke Perf

nuke-debug's sibling for speed (map: references/family-map.md — a self-contained loop). The cheap-model failure mode it corrects: "optimizing" by idiom — sprinkling caches, memoization, and Promise.all on cold paths — and claiming victory without a number. The iron law mirrors debug's: no optimization without a measurement, and the fix phase is unreachable until a baseline exists. A perf claim without before/after numbers from the same harness is a guess wearing a diff.

Arguments

[mode] — light (default) | full | plan (preflight, print, STOP). <target> — the slow thing: a command, endpoint, test, function, or user-visible symptom ("cold start takes 9s"). --ask — pause at the preflight plan for confirmation; default is no gate — the plan prints and the run starts (references/preflight.md).
