LightVision

Fixed

• LightVision did not start on Spigot. Messages are written in MiniMessage, which is part of Adventure, and Adventure ships with Paper only. onEnable built the messenger before it registered the command, so on Spigot the plugin died there with a NoClassDefFoundError and left /lv answering with nothing but the usage line from plugin.yml. MiniMessage is now shaded into the plugin and its output is converted to legacy color codes before it is sent, so the same messages go out on both platforms. Gradients, nested tags and formatting keep working.
• /lv block and /lv unblock used a Paper-only lookup to resolve an offline player. Names are now matched against the online players and the players the server already knows about, still without ever asking Mojang.

Changed

• Built against the Spigot API instead of the Paper API. Nothing in the plugin needed Paper, and building against the smaller API means a Paper-only call cannot slip in unnoticed again.
• Titles and the actionbar go through the Bukkit and Spigot APIs, which Paper and Spigot both provide. Title timings are unchanged.

Paper servers were never affected and see no difference beyond the fixed offline lookup.
