feat: add freecad-mcp to Crush integration

Build and validate FreeCAD MCP Server (v1.25.0).

Changes:
- mcp-freecad-wrapper.sh: Created wrapper script with container cleanup
- crush.json: Added freecad-mcp entry with type: stdio and timeout: 180
- STATUS.md: Updated working MCP list and detailed status table
- JOURNAL.md: Documented integration with full validation results

Validation:
- Container builds successfully (317MB, Python + uv)
- MCP protocol handshake verified with initialize request
- Protocol version 2024-11-05 confirmed
- Server name: FreeCADMCP, version 1.25.0
- Wrapper script tested and working
- Environment variable: PYTHONUNBUFFERED=1
- External dependency: FreeCAD with MCP addon (warning if not running)

Similar to blender-mcp:
- Both Python-based with uv package manager
- Both require CAD application with addon running
- Both show warning on startup when CAD app not connected
- Both still initialize properly for MCP protocol handshake

This is second MCP added in alphabetical order after filtering
out already working MCPs (audiobook, bitwarden, blender, cloudron,
context7, docker, drawio, elasticsearch).

Following ADR-007: Sequential Server Validation - one MCP at a time,
awaiting user validation before proceeding to next MCP.

+### [MCP Integration] freecad-mcp Added and Validated
+
+**Date/Time**: 2026-01-23 01:50:00 PM EST
+**Type**: MCP Integration
+**Status**: Completed - Awaiting User Validation
+
+**What Was Done**:
+Added freecad-mcp (FreeCAD MCP Server) to Crush integration as second MCP in alphabetical order.
+
+**Work Completed**:
+
+1. **Built container**:
+```bash
+docker compose build freecad-mcp
+```
+Result: Successfully built (317MB, Python + uv package manager)
+
+2. **Created wrapper script**:
+- File: `mcp-freecad-wrapper.sh`
+- Pattern: Same as working MCP wrappers (container cleanup, explicit naming)
+- Environment variables: PYTHONUNBUFFERED=1
+
+3. **Tested MCP protocol**:
+```bash
+echo '{"jsonrpc":"2.0","method":"initialize",...}' | \
+  timeout 10 docker run --rm -i kneldevstack-aimiddleware-freecad-mcp
+```
+Result: Valid JSON-RPC response returned (FreeCADMCP v1.25.0, protocol version 2024-11-05)
+
+4. **Added to crush.json**:
+```json
+"freecad": {
+  "type": "stdio",
+  "command": "/path/to/mcp-freecad-wrapper.sh",
+  "timeout": 180
+}
+```
+
+5. **Updated documentation**:
+- STATUS.md: Added freecad-mcp to "Working MCP Servers" and "Recently Built"
+- JOURNAL.md: This entry
+
+**Server Details**:
+- Name: FreeCAD MCP Server
+- Version: 1.25.0
+- Purpose: FreeCAD CAD modeling integration through Model Context Protocol
+- Type: stdio-based MCP
+- Size: 317MB
+- Build: Python with uv package manager
+- Environment Variables Required:
+  - PYTHONUNBUFFERED=1 (for proper Python output buffering)
+- External Service Required: FreeCAD with MCP addon running
+
+**Validation Results**:
+- Container builds: ✓
+- MCP protocol handshake: ✓
+- Wrapper script execution: ✓
+- JSON-RPC initialize response: ✓
+- Protocol version: 2024-11-05 ✓
+- Server capabilities returned: ✓
+- Warning message (expected): Could not connect to FreeCAD (addon not running)
+
+**Files Created**:
+- `/home/charles/Projects/KNEL/KNEL-AIMiddleware/mcp-freecad-wrapper.sh` (executable)
+
+**Files Modified**:
+- `/home/charles/Projects/KNEL/KNEL-AIMiddleware/crush.json` (added freecad entry)
+- `/home/charles/Projects/KNEL/KNEL-AIMiddleware/STATUS.md` (updated status)
+
+**Next Steps**:
+- **User Action**: Validate freecad-mcp in Crush
+- **User Authorization**: After validation, proceed to next MCP (ghost-mcp)
+
+**Working MCPs to Date** (9 total):
+1. audiobook-mcp
+2. bitwarden-mcp
+3. blender-mcp
+4. cloudron-mcp
+5. context7-mcp
+6. docker-mcp
+7. drawio-mcp
+8. elasticsearch-mcp
+9. **freecad-mcp** (NEW - awaiting validation)
+
+**Remaining MCPs** (alphabetical order, filtering out working):
+- ghost-mcp
+- gimp-mcp
+- imap-mcp
+- kicad-mcp (special case: host-only, requires KiCAD running)
+- mcp-ansible (ansibe-mcp)
+- mcp-redmine (redmine-mcp)
+- matomo-mcp
+- nextcloud-mcp (special case: HTTP-based)
+- discourse-mcp
+- docspace-mcp
+- penpot-mcp
+- postizz-mcp
+- proxmox-mcp
+- snipeit-mcp
+- terraform-mcp
+- wordpress-mcp
+- kubernetes-mcp (special case: requires kube config)
+
+**Pattern Applied**: ADR-007 (Sequential Server Validation) - one MCP at a time, validate before proceeding.
+
+**Similarities to blender-mcp**:
+- Both Python-based with uv package manager
+- Both require CAD application with addon running
+- Both show warning on startup when CAD app not connected
+- Both still initialize properly for MCP protocol handshake
