Summary

Implement pre-release versioning for the HVE-Core VS Code extension using EVEN/ODD minor version strategy with agent maturity filtering.

Goals

• Enable VS Code Marketplace pre-release publishing with --pre-release flag
• Implement agent maturity levels via frontmatter metadata (stable/preview/experimental)
• Create build-time agent filtering for stable vs pre-release packages
• Update packaging scripts to support EVEN/ODD minor version strategy
• Create GitHub Actions workflow for pre-release publishing
• Update documentation for contributors

Technical Approach

• EVEN minor versions (1.0.x, 1.2.x) = Stable releases
• ODD minor versions (1.1.x, 1.3.x) = Pre-release channel

See research document: .copilot-tracking/research/20260114-prerelease-versioning-research.md

Acceptance Criteria

• Pre-release extension packages include --pre-release flag
• Stable builds exclude experimental/preview agents
• Pre-release builds include all non-deprecated agents
• Documentation enables contributors to use maturity system
