Continues the Bookshelf history. The three plugins tracked there are consolidated into umbra-bookshelf/ and this repository becomes the canonical home for the plugin and the theme. bd-bookshelf/ -> theme/ separate artifact, name unchanged (root specs) -> umbra-bookshelf/spec/ aligned to Umbra Bookshelf old plugin zips -> archive/pre-umbra-releases/ Adds a repository README and drops the Bookshelf closure notice.
