Jon Chery 0b58286ca2 feat(P04): --pprof opt-in on orca daemon (REQ-056, I-308)
Separate *http.Server + *http.ServeMux (AD-024), default disabled.
Operator opts in via --pprof <addr>. WARN logged on startup. All pprof
handlers explicitly registered on dedicated mux (no DefaultServeMux
side-effect). I-308 deferred since v0.2 now implemented. 6 new tests.
