bigbang 0.1.0

bigbang — create custom R metapackages from local packages

Data-safety architecture

• Removed all generated startup installation and cwd-relative cleanup. Generated .onLoad() hooks are side-effect free; component installation is explicit via <meta>_install().
• Added destructive regression tests in disposable directories, including real source installation, attachment, data-only components, names beginning with tmp, and content hashes for decoy directories.
• Added scan_bigbang_artifact() to identify the historical V1/V2/V3/V7 signatures in source trees, archives, and installed packages without loading them.
• Generated projects must use a new or empty destination, preventing unsafe in-place regeneration of unclassified historical sources.

Installation and portability

• Component archives are installed once in topological dependency order; cycles raise a typed bigbang_error_cycle condition.
• Added explicit offline dependency policies (skip, error, install) and content-based distinction between source ZIPs and Windows binary ZIPs.
• All generated text is written as UTF-8, R literals and paths are emitted safely, and CI covers Linux, Windows, and macOS configurations.

API, language, and documentation

• Added the English snake_case API: create_metapackage(), install_local_pkg(), and diagnose_dependencies(). Spanish aliases remain available as deprecated transition wrappers.
• Added typed results and conditions with print methods.
• English is the source language. Spanish runtime translations are supplied through gettext for both bigbang and generated metapackages.
• Added English and Spanish guides, release documentation, and a pkgdown configuration.
