docs: enhanced reference documentation with implementation details

Added comprehensive implementation guidance to reference docs:
- MCP-GITEA.md: Token generation steps, Python requirements, server implementation, async wrappers, branch detection
- MCP-WIKIJS.md: Token generation steps, Wiki.js structure setup script, initialization guide
- PLUGIN-PMO.md & PLUGIN-PROJMAN.md: Updated plugin manifests and configuration details
- PROJECT-SUMMARY.md: Consolidated project status and architecture decisions

These updates prepare the reference materials for Phase 1 implementation.

+**Key Differences from projman:**
+- `dependencies`: Declares dependency on projman plugin
+- No `GITEA_REPO` or `WIKIJS_PROJECT` in configuration (company-wide mode)
+- Focused on coordination, not individual project management
