MC 26.1 changed the minecraft:slot_display registry, inserting 3 new
types (with_any_potion, only_with_component, dyed) and shifting all
existing IDs. This caused MCC to misparse recipe display data, leading
to a Queue empty crash in SkipItemHolderSet.
Add version-gated ReadSlotDisplayLabel with correct 26.1 type mapping
and reader methods for the 3 new slot display types.

- Introduced a new `ServerStatusInfo` class to encapsulate server status data including MOTD, player counts, and version information.
- Implemented `ServerStatusDisplay` to format and display server status information in both classic and TUI modes.
- Added protocol version upgrade logic in `ProtocolHandler` to determine the highest supported protocol version for multi-version servers.
- Updated translations to support new server status labels and messages.
- Created `ServerStatusPanelBuilder` for TUI to visually represent server status with player information and connection details.
- Updated explosion packet processing to accommodate changes in Minecraft protocol versions, specifically for versions 1.21.2 and 1.20.4.
- Removed obsolete fields such as explosion strength and block records for newer versions, and added support for optional knockback and particle data.
- Enhanced backward compatibility for earlier versions by maintaining existing logic for explosion data retrieval.
- Updated the Container class to include a protocol version parameter for accurate container type mapping.
- Modified the GetContainerType method to account for changes in container types introduced in Minecraft 1.20.4.
- Added new container types, including Crafter, to the ContainerType enum.
- Adjusted ContainerTypeExtensions to reflect the new container mappings and ensure compatibility with the updated protocol.
- Added support for the new world border hit flag in Protocol18 for protocol version 1.21.2.
- Updated SocketWrapper to throw a SocketException if SendDataRAW is called when not connected, improving error handling.
These changes enhance the protocol handling and error management in the Minecraft Console Client.
Adds a MaxChatMessageLength config option under [Main.Advanced] that allows
users to override the protocol-defined maximum chat message length. Default is
0 (auto: 100 for MC 1.10 and below, 256 for MC 1.11+). Some servers like
Hypixel support longer messages on older versions, so this lets users set a
custom limit (e.g. 256 on 1.8.9). Includes a warning about potential kicks
if set incorrectly.
Closes#2947

Replace lowercase primary constructor parameter references (dataTypes.,
subComponentRegistry., itemPalette.) with PascalCase base class property
references (DataTypes., SubComponentRegistry., ItemPalette.) in method
bodies of all StructuredComponent and SubComponent subclasses.
This eliminates CS9107 warnings where subclass primary constructor
parameters shadow the base class properties they are assigned to.

Convert remaining == null to is null and != null to is not null
across 17 files in CommandHandler/ArgumentType, StructuredComponents,
and DeclareCommands for idiomatic C# style.

Replace explicit constructor calls with target-typed new() expressions
where the type is already specified on the left side of the assignment.
This is a C# 9+ feature that reduces redundancy.
Files changed:
- Container.cs: field assignments in constructors
- EntityPalette18/112/113.cs: static field initializers
- ChatParser.cs: StringBuilder local variable
- Movement.cs: field assignments in constructor
- PacketPalette18.cs: field initializers
- EnchantmentMapping.cs: field reassignments

- DirectionExtensions.cs: Convert GetOpposite() to switch expression,
use file-scoped namespace, use collection expression for HORIZONTAL
- McClient.cs: Convert InteractType switch to expression, use collection
expressions for array literals
- Protocol18.cs: Replace Array.Empty<byte>() with [], use collection
expressions for byte/int array literals
- DataTypes.cs: Use collection expression for TAG_End byte array
- ChatBot.cs: Use collection expressions for string/char arrays
- Location.cs: Use collection expressions and modernize null check

Replace '== null' with 'is null' and '!= null' with 'is not null'
across 19 core files following modern C# pattern matching conventions.
Only literal null comparisons are changed. Assignments, value
comparisons, and LINQ expressions are left untouched.

Replace all lock object declarations using 'object' type with the C# 13
System.Threading.Lock type across 12 files. The Lock type provides a
more efficient locking mechanism - when used with lock(), the compiler
automatically uses Lock.EnterScope() instead of Monitor.Enter/Exit.
Also made two previously non-readonly lock fields readonly:
- McClient.DigLock
- Protocol18.MessageSigningLock

- Rewrite Json.cs to use System.Text.Json.Nodes (JsonNode, JsonObject, JsonArray)
- Add JsonNodeExtensions.GetStringValue() for backward-compatible string access
- Update all 14 consumer files to use the new JsonNode API
- Remove ~300 lines of hand-rolled JSON parsing code from 2013
- Replace KeyUtils.EscapeString with delegation to Json.EscapeString

- Protocol18: add MC_26_1_Version constant (775), version-gated palette
routing for blocks/items/entities/metadata, and new TimeUpdate packet
format (WorldClock map replaces dayTime+tickDayTime)
- Protocol18Terrain: read new fluidCount short in chunk sections (26.1+)
- DataTypes: add CatSoundVariant to entity metadata VarInt readers
- ProtocolHandler: add NormalizeSnapshotProtocol() to map RC/snapshot
protocol numbers (e.g. 0x4000012E → 775) to release versions, pass
raw protocol version through for server handshake compatibility

Add PacketPalette261 with new packet types (GameRuleValues, LowDiskSpaceWarning,
Attack, SetGameRule). Create StructuredComponentsRegistry261 with 6 new components
(additional_trade_cost, dye, pig/cow/chicken/cat sound_variant). Update version
routing in PacketType18Handler, EntityMetadataPalette, StructuredComponentsHandler,
and Program.cs to support protocol 775 (26.1).

- Introduced a comprehensive physics engine that replicates Minecraft's movement mechanics, including player input handling, gravity, and collision detection.
- Added classes for player physics, movement input, and collision detection, ensuring accurate simulation of player interactions with the game world.
- Integrated AABB (Axis-Aligned Bounding Box) structures for precise collision detection against blocks.
- Enhanced movement capabilities with support for jumping, sneaking, and sprinting, along with step-up mechanics for navigating terrain.
These changes significantly improve the realism and responsiveness of player movement within the game environment.
Two bugs fixed:
1. EnchantmentsComponent was reading a trailing ShowTooltip boolean that
was removed from the wire format in MC 1.21.5. Created
EnchantmentsComponent1215 and StoredEnchantmentsComponent1215 that
omit the boolean. Used by StructuredComponentsRegistry1215 and 12111.
2. MC 1.21.5+ changed ServerboundContainerClickPacket to use HashedStack
(item holder id + count + hashed component patch map) instead of full
ItemStack for changed slots and carried item. Added GetHashedItemSlot()
in DataTypes.cs and gated SendWindowAction in Protocol18.cs to use it
for 1.21.5+. Since MCC doesn't track component hashes, an empty
HashedPatchMap is sent; the server detects stateId mismatch and resyncs.
Tested: AutoFishing bot successfully catches fish on MC 1.21.11 with
enchanted fishing rods (Lure III + Luck of the Sea III).
