Here it is:
sv_enablebunnyhopping 1 (most important, use sm_cvar as it's locked)
sv_airaccelerate 150 (strafing)
sv_maxvelocity 1000 (max reachable speed, adjust to your needs)

+ the stamina part:
sv_staminajumpcost 0
sv_staminalandcost 0

Perfect bunny hopping will still be hard, but you will be able to gain speed with that config.
