Poison cooldown reduced

This update gives poison a lighter buff by making it available more often without extending its control window.

Changes:

• Poison duration remains 4 frames.
• Poison cooldown reduced from 40 frames to 34 frames.
• Poison still slows the enemy action cadence: while poisoned, the enemy skips action commands on roughly half of the affected frames.

This keeps poison from becoming a longer lockout while making it easier to use multiple times in a match. It remains a tempo tool for disrupting movement, turning, firing, or skill timing while still leaving the opponent room to act.
