BindAlias 1.8.6 для Minecraft 1.21.11 (Fabric)

Added

• Per-save agent cfg — a second cfg file at `<game_root>/saves//bind-alias/agent.cfg` loads alongside the main cfg on world join. The maintainer can place initialization details in global cfg that are hidden from the MCP agent.
• MCP /readNotes and /writeNotes tools — read/write arbitrary text files inside the per-save agent directory (`<game_root>/saves//bind-alias/). Only plain filenames (no path separators, no ..`) are accepted.

Changed

• MCP readCFG/writeCFG scope — both tools now operate exclusively on the per-save agent cfg file and require the player to be in a singleplayer world. The maintainer can place initialization details in global cfg that are hidden from the MCP agent.
• held_keys no longer includes +freeCursor — the internal +freeCursor toggle is hidden from the standard envelope to avoid confusing the agent with unnecessary state.
• Bridge tool instructions cleaned — removed +-freeCursor and reapply from the MCP bridge descriptions since they are developer-oriented and not useful to MCP agents.

Fixed

• +use missing from held_keys in the MCP envelope.
• POST MCP tools timing out — req.end() was missing from the bridge's apiPost, causing all POST-based tools (runAlias, writeCFG, defineAlias, writeNotes) to hang indefinitely.
• writeCFG/writeNotes bridge timeout increased from 10s to 30s to accommodate per-save cfg reload.
