chore: detach issue-facade capability for reorganization

Detach issue-facade from capabilities/ directory in preparation for
re-integration using new ReusableCapabilitiesArchitecture pattern.

Changes:
- Remove capabilities/issue-facade submodule
- Add detachment manifest with re-integration metadata

Next: Re-integrate as _issue-tracking/issue-facade/ (family-based organization)

Detachment manifest: capabilities/DETACHED-issue-facade.yaml

+  To re-integrate this capability using the new architecture:
+
+  # Option 1: Git submodule (recommended)
+  cd /home/worsch/markitect_project/capabilities
+  git submodule add <repo-url> _issue-facade
+  pip install -e _issue-facade/
+
+  # Option 2: Clone directly
+  cd /home/worsch/markitect_project/capabilities
+  git clone <repo-url> _issue-facade
+  pip install -e _issue-facade/
+
+  # Option 3: Copy into project
+  cd /home/worsch/markitect_project/capabilities
+  cp -r /path/to/issue-facade _issue-facade
+  pip install -e _issue-facade/
+
+  Note: Use underscore prefix (_issue-facade) per ReusableCapabilitiesArchitecture
+
+notes:
+  - The original integration used pattern: capabilities-directory
+  - New architecture recommends: underscore-prefix at repo root
+  - See ReusableCapabilitiesArchitecture.md for details
