v0.6.4

Changed

• augent install: When run from a subdirectory containing bundle resources, or when specifying a local path (e.g., augent install ./my-bundle), only that bundle and its dependencies are installed. The workspace bundle is not installed in these cases.
• Workspace bundle names are now automatically inferred from workspace location (git remote or directory name) rather than stored in configuration files. This eliminates synchronization issues and simplifies workspace configuration management.
