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.

+### Added
+- **projman:** New feature description
+- **plugin-name:** Another feature

+- **projman:** Modified behavior

+- **plugin-name:** Bug fix description

+**IMPORTANT:** Never skip this step. Every sprint must update CHANGELOG.

+**H. Version Check**
+
+Run `/suggest-version` to analyze CHANGELOG and recommend version bump:
+```
+/suggest-version
+```
+
+If release is warranted:
+```bash
+./scripts/release.sh X.Y.Z
+```
+
+This ensures version numbers stay in sync:
+- README.md title
+- .claude-plugin/marketplace.json
+- Git tags
+- CHANGELOG.md section header
