dewei-zhu

Summary

dewei-zhu works almost entirely on WebKit's build and performance tooling rather than engine code: PGO profile collection and discovery (`collect-pgo-profiles`, directory-structure independence, framework discovery), PGO exclusions for JavaScriptCoreTools, and the `run-benchmark` harness including per-iteration reporting and an SSH-execution hang fix. The JSC-tagged commit is a build-configuration change, not a change to the engine itself, and nothing in the recent history touches memory safety, parsing, or JIT semantics. This is infrastructure work with no security or hardening surface to sweep.
