DCRP-27: Critical-Reservoir Absorption and Type-II Euler–Reynolds Reprofiling

Removes 'critical-reservoir blowup' as an undifferentiated escape label, proves that bounded local energy and pressure reservoirs force an eventual uniform dissipation bound along a nested chain, and reprofiles the kinetic-energy Type-II branch, via Euler-time normalization, into a local Euler or Euler–Reynolds defect object.
