Fix build-time version binding system

- Remove compiler flag warnings from Package.swift
- Implement file-based version system with BuildInfo.swift
- Fix version function duplication in build scripts
- Add instruction layer and single-prompt mode
- Version now correctly auto-generated from git tags
