perf-optimizer

Systematic performance optimization and regression debugging for the OneKey mobile app (iOS). Use when: (1) fixing performance regressions — when metrics such as tokensStartMs, tokensSpanMs, or functionCallCount have regressed and must be restored to normal levels; (2) improving baseline performance — when you need to optimize cold start time or reduce function call overhead; (3) responding to user requests for performance improvements or debugging of the app startup or home screen refresh flow.
