fix: remove hardcoded paths, gitignore binaries

- Add paths.go with WorkspaceRoot(), CoreRoot(), PlansRoot()
- All workspace paths now check CORE_WORKSPACE env var first
- Fallback: ~/Code/.core/workspace (works on any machine)
- Remove committed core-agent and mcp binaries from tracking
- Add .gitignore for compiled binaries
