The filer-side mount peer registry (tier 1 of peer chunk sharing) was gated behind -mount.p2p (default true). Idle cost is negligible — a tiny in-memory map plus a 60s sweeper — so the opt-out is not worth the surface area. Removes the flag from weed filer, weed server (-filer.mount.p2p), and weed mini, and always constructs the registry in NewFilerServer. Also drops the now-dead nil guards in MountRegister/MountList/sweeper and the TestMountRegister_DisabledIsNoOp case.
