Party Extension for Duels Optimized 1.16.2

✦ New Feature: Party Invite System

No more relying on the chat broadcast getting buried in conversation, invite players directly.

Commands

• /fp invite <player> sends a clickable invite to a specific player
• /fp invite all invites every online player at once (off by default, opt-in via config)
• Clicking an invite joins the party through the normal join path, so your whitelist/blacklist still applies

Built-In Spam Controls

• 30-second per-target cooldown, re-inviting the same player tells you how long to wait instead of just "already invited"
• 120-second cooldown between /fp invite all uses on the same party
• Auto-skips players already in a party or match
• Stops sending invites once your party is full
• Configurable title and sound when someone gets invited

✦ New Config

invites:
  allow-invite-all: false   # flip to true to enable /fp invite all

Plus configurable invite title, sound, and cooldown values, all auto-migrated on first startup.
