- 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).

- Revised the SKILL.md file to enhance clarity and detail regarding the development workflow for Minecraft Console Client (MCC).
- Expanded sections on project structure, build commands, and debugging steps, including specific instructions for compiling, starting a test server, and running MCC.
- Added environment setup details and a checklist for server configuration, improving usability for developers.
- Included new tools and scripts for server management and decompilation processes, streamlining the development experience.
These updates provide comprehensive guidance for developers working with MCC in WSL.
- Adjusted the indexing logic in BlockShapes.cs to ensure proper mapping of state counts to shape IDs.
- Introduced a global state offset to accurately reference shape IDs in the list, preventing out-of-bounds errors during shape assignment.
These changes enhance the reliability of block shape processing in the physics engine.
- Introduced a new `.cursorindexingignore` file to prevent indexing of SpecStory auto-save files while allowing explicit context inclusion via @ references.
- Updated `.gitignore` to exclude the entire `.specstory/` directory and `.vscode/settings.json`, ensuring these files are not tracked by Git.
These changes help streamline project management by excluding unnecessary files from indexing and version control.
- 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.
- Introduced `decompile.sh` to automate the decompilation process, including downloading `MinecraftDecompiler.jar` and server.jar for specified Minecraft versions.
- Added `mc-rcon.sh` for sending RCON commands to a Minecraft server, improving server management capabilities.
- Created `mcc-env.sh` to provide helper functions for managing Minecraft servers, including starting, stopping, and sending commands.
- Implemented `start-server.sh` to launch a Minecraft server in a tmux session with a named pipe for stdin, facilitating easier command input.
- Updated `README.md` to reflect new tools and usage instructions for decompiling and server management.
These changes streamline the workflow for adapting to new Minecraft versions and enhance the overall development experience.
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).
