fix(projman): add mandatory CHANGELOG and versioning to sprint-close workflow

Problem: Version workflow was documented but not enforced in sprint-close.
After completing sprints, CHANGELOG wasn't updated and releases weren't created.

Solution:
- Add "Update CHANGELOG" as mandatory step 7 in sprint-close
- Add "Version Check" as step 8 with /suggest-version and release.sh
- Update orchestrator agent with CHANGELOG and version reminders
- Add V04.1.0 wiki workflow changes to CHANGELOG [Unreleased]
- Document MCP bug #160 in Known Issues

This ensures versioning workflow is part of the sprint close process,
not just documented in CLAUDE.md.
