hw/cp: engine retires on resource done, not on arbiter grant

docs: pure-v2 callbacks_t + software CP for simx/rtlsim

sim/common: software CommandProcessor C++ class + unit test

runtime: add cp_mmio_write/read callbacks; wire all 4 backends

runtime: dispatcher owns CP ring submission; Queue routes through it when VORTEX_USE_CP=1

hw/cp: VX_cp_dcr_proxy latches addr+data on grant (was sampling zeros in S_REQ)

runtime: strip legacy launch_/dcr_ from callbacks_t (Phase E — pure v2)

cp: release-style comments and consolidated design doc

hw/cp: add VX_cp_event_unit and VX_cp_profiling skeletons
