Release v1.3.3 - Fix MCP protocol compliance

Critical fix: MCP SDK now external (not bundled/obfuscated)
- Added --external:@modelcontextprotocol/sdk to esbuild
- MCP SDK loads from node_modules at runtime
- Tools now register correctly in all MCP clients
- Bundle size reduced: 5.3MB → 2.3MB
- Full obfuscation maintained for proprietary code only

Industry best practice: Externalize protocol libs, obfuscate proprietary code

+## [1.3.3] - 2025-10-09
+
+**Critical Fix - MCP Tool Registration**
+
+### Fixed
+- **Tool Registration Failure**: MCP SDK was bundled and obfuscated, breaking protocol compliance
+- **External MCP SDK**: MCP SDK now excluded from bundling (loaded at runtime)
+- **Bundle Size**: Reduced from 5.3MB to 2.3MB by externalizing SDK
+- **Client Detection**: MCP clients now properly detect and list available tools
+
+### Technical Changes
+- Added `--external:@modelcontextprotocol/sdk` to esbuild configuration
+- MCP SDK loads from node_modules at runtime (not bundled)
+- Reserved names for tool response format (content, structuredContent, isError)
+- Maintained full obfuscation for proprietary instruction content only
+
+### Why This Matters
+**Problem**: v1.3.2 bundled and obfuscated the entire MCP SDK, breaking JSON-RPC protocol compliance and tool registration.
+
+**Solution**: Industry best practice - externalize protocol libraries, obfuscate proprietary code only. MCP SDK loads at runtime while instruction content remains fully protected.
+
+**Result**: MCP protocol compliance maintained + proprietary content protected = tools work correctly with IP protection.
