Changed

• Migrated all player messaging from legacy §-code strings to Adventure API (Component/MiniMessage) across all command and listener classes
• Migrated UpdateNotificationListener from BungeeCord chat API to Adventure API (ClickEvent, HoverEvent, Component builder)
• Fixed InfiniteRestockFeature blacklist GUI: statusText/statusColor now use MiniMessage tags (<red>, <green>) instead of §-codes so they render correctly when passed to MessageManager.parse()
• Item Limiter: findMatchingItemKey no longer scans all configured limits linearly. A Material → key index is built at load time so lookups are O(1) for the common case instead of O(n limits)
• Item Limiter: inventory scan is now distributed across ticks (1 player per tick) instead of checking every online player in a single 20-tick burst
• Item Limiter: getPlayerItemCount no longer re-runs findMatchingItemKey for each inventory slot — the target limit is resolved once and ItemLimit.matches() is used directly
• Item Limiter: potion material detection replaced toString().contains("POTION") with a proper EnumSet<Material> covering POTION, SPLASH_POTION, and LINGERING_POTION
• Completed Adventure API migration: replaced all remaining legacy § color codes in ServerRestartFeature, ShieldMechanicsFeature, MinimapControlFeature, ItemLimiterListener, MaceLimiterListener, InvisibleKillsFeature, and MainMenu with MiniMessage format; GUI title constants in MaceLimiterFeature, ShieldMechanicsFeature, MobManagerFeature, and ServerRestartFeature converted from §-coded strings to Component constants; corresponding listeners updated to use InventoryView.title() (Component API) for title matching
• ServerRestartFeature: migrated from BungeeCord ActionBar API and Bukkit BossBar to Adventure API (player.sendActionBar, player.showTitle, net.kyori.adventure.bossbar.BossBar)
• MainMenu: replaced deprecated getLore() + §-detection with lore() + PlainTextComponentSerializer for lore inspection
• config.yml: migrated all message values from § codes to MiniMessage format
• Added JUnit 5 (junit-jupiter:5.10.0) as a test dependency
• ServerRestartListener: replaced non-thread-safe HashMap with ConcurrentHashMap for awaitingInput; async chat handler now uses atomic remove-and-null-check pattern to eliminate TOCTOU race
• UpdateNotificationListener: CDN-provided title and message text is now escaped with MiniMessage.escapeTags() before parsing to prevent tag injection
• MinimapControlFeature: world name, environment, and minimap mode values are escaped with MiniMessage.escapeTags() before being embedded in MiniMessage strings
• MessageManager.get(String, Object...): now throws IllegalArgumentException immediately when an odd number of replacement arguments is supplied or a key is null, instead of silently ignoring the trailing argument
• ShieldMechanicsFeature: extracted shared stun-lore assembly into buildStunLore(boolean, int) helper to eliminate duplication between buildMaceStunItem and buildAxeStunItem
• ServerRestartFeature.getRestartMessage: consolidated {time} and {player} substitution into a single overloaded method; callers no longer chain .replace("{player}", ...) at the call site
• MobManagerFeature.onRightClick: disabled warning now uses the centralized mob-manager.feature-disabled messages.yml key instead of a hardcoded literal
• InfiniteRestockFeature, ItemLimiterFeature: fillBorder now uses meta.displayName(Component.empty()) instead of the deprecated meta.setDisplayName(" ")
• messages.yml: removed UTF-8 BOM from file header

Fixed

• VanillaCommand reload: each feature's reload() is now wrapped in its own try/catch; a failure in one feature no longer aborts the reload loop for all subsequent features
• MainMenu: removed unreachable duplicate slot-50 handler that could never be reached after the earlier slot-50 Wiki handler returned
• MainMenu: removed duplicate import net.kyori.adventure.text.Component import

Added

• Fixed DimensionLockConfig default lockedMessage values to use MiniMessage (<red>The End/Nether is currently locked!)
• Fixed InvisibleKillsConfig default deathMessage to use MiniMessage ({victim} was killed by <obfuscated>?????????)
• Documentation: updated all §-coded examples in docs/docs/configuration.md to MiniMessage format
