Bounty: admin stop command

• Added /biotrace bounty stop (op level 2) to cancel an active bounty
• Clears the bounty HUD for all players and broadcasts a chat message
• Applies the normal bounty cooldown before the next automatic bounty
• Returns an error if there is no active bounty

Bounty: disconnect grace & anti-flee

Bounty no longer ends immediately when the target disconnects

• 60-second grace period after disconnect (config: bountyDisconnectGraceSeconds)

• During grace, the bounty timer keeps running

• After grace, if the target is still offline, the bounty pauses and waits for them to return
• On reconnect, the bounty resumes with remaining time
• Chat notifications when a bounty is paused and resumed
• Bounty HUD updates:

• TARGET OFFLINE during grace

• PAUSED when the timer is frozen

• Gray/frozen timer while paused

Bounty: auto-trigger threshold

• Minimum online players for automatic random bounties raised from 2 → 5 (bountyMinOnlinePlayers)
• Admin bounty commands (create, trigger) are unchanged and still work with fewer players

Technical notes

• Bounty stop and disconnect handling are server-authoritative; clients only receive synced HUD state
• Pause/resume state is saved and survives server restarts
