docs: document kicad-mcp as host-only MCP

kicad-mcp requires the pcbnew Python module which is only
available with a KiCAD installation. The container builds
successfully but fails validation because pcbnew cannot be
pip-installed or included in the container.

- Added "Host-Only MCP Servers" section to STATUS.md
- Updated detailed status table with kicad-mcp entry
- Added JOURNAL.md entry documenting the finding
- Updated docker-compose.yml to use custom Dockerfile

This MCP can only be used on a host machine with KiCAD
installed. It cannot be integrated into Crush via Docker.

Build details:
- Container size: 463MB
- Base: node:22-alpine with Python 3 + pip
- Dependencies: kicad-skip, Pillow, cairosvg, colorlog, pydantic

Validation error:
[ERROR] pcbnew validation failed: ModuleNotFoundError: No module named 'pcbnew'

Root cause:
- KiCAD's pcbnew is a C++ Python binding bundled with KiCAD
- Cannot be installed via pip or any package manager
- Server validates pcbnew at startup and exits if missing

Pattern identified:
Some MCPs integrate with desktop applications and cannot
be containerized. These should be documented as host-only
and excluded from Docker-based Crush integration.

Next MCP to process: matomo-mcp

💘 Generated with Crush

+### [MCP Integration] kicad-mcp - Host-Only MCP (Cannot Containerize)
+
+**Date/Time**: 2026-02-17 10:30:00 AM EST
+**Type**: MCP Integration
+**Status**: Cannot Containerize - Requires KiCAD on Host
+
+**What was done**:
+1. Cloned kicad-mcp vendor repository
+2. Built container successfully (463MB)
+3. Attempted MCP protocol validation
+4. Discovered containerization blocker
+
+**Build Details**:
+- Base image: node:22-alpine with Python 3 + pip
+- Container size: 463MB
+- Dependencies installed: kicad-skip, Pillow, cairosvg, colorlog, pydantic, requests, python-dotenv
+- Build succeeded without errors
+
+**Validation Result**: FAILED
+```
+[ERROR] pcbnew validation failed: Command failed: "/usr/bin/python3" -c "import pcbnew; print('OK')"
+ModuleNotFoundError: No module named 'pcbnew'
+```
+
+**Root Cause Analysis**:
+- KiCAD's `pcbnew` module is a C++ Python binding that comes bundled with KiCAD
+- Cannot be installed via pip or any package manager
+- The MCP server validates pcbnew availability at startup and exits if missing
+- No workaround exists - pcbnew requires a full KiCAD installation
+
+**Conclusion**: kicad-mcp is a **host-only MCP** that:
+- Cannot be run containerized
+- Requires KiCAD installed on the host machine
+- Can still be used with Crush if KiCAD is installed on the host
+- Must be configured differently (direct execution, not Docker)
+
+**Files Modified**:
+- STATUS.md: Added "Host-Only MCP Servers" section with kicad-mcp entry
+- STATUS.md: Added kicad-mcp to detailed status table
+
+**Pattern Identified**:
+Some MCPs are designed to integrate with desktop applications and cannot be containerized. These should be:
+1. Documented as host-only in STATUS.md
+2. Not added to crush.json (or added with direct execution, not Docker)
+3. Clearly marked to prevent confusion
+
+**Next MCP**: matomo-mcp
