fix: redirect MCP server logs to stderr to preserve JSON-RPC protocol

MCP uses stdio transport where stdout is reserved for JSON-RPC messages.
Console.log was writing startup logs to stdout, causing Claude Desktop
to parse "[2025-12-19..." as a JSON array and fail.

Fixes #396

+
+## What's New
+
+### MCP Tool Token Reduction
+
+Optimized MCP tool definitions for reduced token consumption in Claude Code sessions through progressive parameter disclosure.
+
+**Changes:**
+- Streamlined MCP tool schemas with minimal inline definitions
+- Added `get_schema()` tool for on-demand parameter documentation
+- Enhanced worker API with operation-based instruction loading
+
+This release improves session efficiency by reducing the token overhead of MCP tool definitions while maintaining full functionality through progressive disclosure.
