feat(cli): add startup performance profiler (#3219) Add a lightweight startup profiler activated via QWEN_CODE_PROFILE_STARTUP=1. When enabled, collects performance.now() timestamps at 7 key phases in main() and writes a JSON report to ~/.qwen/startup-perf/. Also records process.uptime() at T0 to capture module loading time not covered by checkpoint-based measurement. Key design decisions: - Only profiles inside sandbox child process to avoid duplicate reports - initStartupProfiler() is idempotent (resets state on each call) - Filename uses report.sessionId for consistency with JSON content - Zero overhead when disabled (single env var check) Initial measurement: module loading ~1342ms (94%), main() ~85ms (6%), confirming barrel exports and eager dependency loading as primary optimization targets for #3011.
