Docusaurus build fix - Sidebar and missing image issues (#1243)

* fix(docs): align sidebar with actual docs structure and fix image path

Sidebar referenced non-existent paths (modules/bmm/, getting-started/, etc.)
while actual docs live in different locations (modules/bmm-bmad-method/,
bmad-core-concepts/, etc.). Updated sidebar to match reality so Docusaurus
can build successfully.

Also fixed broken image reference in workflows-guide.md that used an
incorrect relative path.

* fix(docs): update build script to include docs/modules directory

The build script was excluding the modules folder when copying from docs/,
but module docs now live in docs/modules/ instead of src/modules/*/docs/.

* fix(docs): correct broken internal links

Fixed relative paths that were pointing to non-existent locations:
- bmgd index: ../../bmm/docs/index.md → ../bmm/index.md
- cis index: ../../bmm/docs/index.md → ../bmm/index.md
- bmm faq: ./README.md → GitHub URL
