feat(balance): restrict eskrima haft strikes to more damaging bash weapons

[chaosvolt]

Purpose of change

Per Pr0man's feedback on the discord, one issue with Eskrima is that the puno strike technique takes a lot of the utility out of using it with knives, as it frequently triggers with crits to completely negate the majority of damage for those weapons.

Describe the solution

Set puno strikes to have weapon_damage_requirements of 8 bashing damage, same as a cudgel. Idea here is to exclude knives from the technique and mainly limit it to weapons that have enough base bashing damage to justify using the technique.

Realistically you could do haft strikes with knives just fine and they can certainly break bones if used right, but it doesn't bear out very well under current gameplay mechanics so it'd be better to reserve them for weapons that work well with it.

Describe alternatives you've considered

1. Coding in support for restricting tecs to specific weapon categories instead to make this a baton-only technique more elegantly.
2. Making it gain a bash damage bonus, simply removing the bash damage penalty, or giving bashing arpen to make the technique more worth it and represent it being used mainly on vulnerable targets of opportunity. Doing so might warrant adding a weighting penalty in exchange.
3. Buffing hollow canes from 3 damage might be good, as it's the only vanilla baton-category weapon that'll really be excluded from this technique.
