RexChat

🐛 Bug Fixes

• Fixed /rexchat global and /rexchat local working when proximity chat is disabled - These subcommands now properly check if chat-management.proximity.enabled is true before executing.
• Fixed /rexchat viewinv and /rexchat viewitem working when chat previews are disabled - These subcommands now check chat-previews.enabled before opening preview GUIs.
• Fixed double permission prefix bug - /rexchat global and /rexchat local were checking rexchat.rexchat.proximity.toggle instead of rexchat.proximity.toggle, making them unusable for non-op players.
• Fixed proximity message config paths - Global/local toggle messages were reading from a non-existent messages.proximity.* path instead of the correct chat-management.proximity.*.

🔧 Improvements

• Removed dead /rexchat inv and /rexchat item subcommands - These were leftover handlers that did nothing. Preview functionality is handled by viewinv/viewitem (triggered via chat clicks).
• Smarter tab completion - Subcommands global/local are now hidden from tab complete when proximity chat is disabled.
• Cleaner help menu - /rexchat help now only shows proximity commands when the feature is enabled.
• Added missing permissions to plugin.yml - rexchat.chat.minimessage, rexchat.chat.placeholders, rexchat.proximity.bypass, and rexchat.proximity.toggle are now properly defined.
• Proximity config validation - ConfigValidator now validates proximity chat settings (enabled, radius, bypass-permission) and reports errors on misconfiguration.
