CoreProtectVisualizer

Added

• Action-based coloring — Green glow for placed blocks, red for broken, cyan for interactions, yellow for unknown. Colors configurable via visualization.action-colors.
• Shulker display engine — Alternative rendering mode using invisible shulkers with glow outlines. Selectable via visualization.engine (block_display or shulker).
• CoreProtect API integration — Plugin now hooks CoreProtect's API as a fallback to determine block types and actions when text parsing is insufficient.
• Message buffering — Per-player buffer keeps recent CoreProtect messages to correctly associate actions/materials with following coordinate lines.
• Configurable coordinate patterns — All regex patterns are now in config.yml; the plugin has no hardcoded patterns. Added the clickable (xNNN/yNNN/zNNN/world) format.
• Hex color support — Block colors and action colors accept #RRGGBB hex values in addition to named colors.
• Configurable fallback material — visualization.default-block-material controls what block type is shown when the original material can't be determined.
• Fully configurable messages — All plugin messages moved to config.yml with & legacy + &#rrggbb hex color support. {count}, {key}, {value} placeholders supported.

Changed

• Render engine — Replaced GlowingEntities (shulker-based) dependency with native Paper BlockDisplay entities. Zero external runtime dependencies for rendering.
• Block color system — Migrated from ChatColor to org.bukkit.Color for full RGB support.
• API version — Bumped from 1.19 to 1.21.
• Message detection — Replaced fragile heuristic (message.contains("CoreProtect")) with pure regex-based coordinate extraction and proper JSON chat component parsing.
• Material parsing — Now handles lowercase material names (e.g. grass_block) from CoreProtect lookup messages.

Removed

• GlowingEntities dependency — No longer bundled; rendering uses native Paper APIs only.
