Velocity Sign Link - v1.3

Added

• Sign Deletion Functionality: Implemented a new command to remove the configuration from a sign. You can now use /deletesign while looking at a sign to unregister it. (Closes #2)
• Configurable "No Data Found" Message Display: Introduced a new permission VeloSign.nomessage. Players with this permission (granted to everyone by default) will not see the "No Data found for this sign" message when clicking a sign. Does not affect the /getsign command. Revoke the permission to show the message. This provides flexible control over this feedback. (Addresses #1)
• Cooldown Display Enhancement: Added a new configuration option display_below_one_second_as_one (default: true). When enabled, cooldowns less than 1 second (e.g., 0.6s) will be displayed as "1 second" rather than "0 seconds".
