Merge branch 'citations-and-sigla'

Citations are parsed into structure and re-rendered, so book names,
abbreviations, punctuation style and numbering tradition become files a
user edits rather than strings frozen in the data.

New lib/citation (Book, Parse, Render, Sigla); [bible] and [sigla]
sections in language files; lang/traditions.ini for numbering; three
config keys and CLI flags. --raw emits every citation byte-for-byte as
stored, bypassing the whole pipeline, so output stays diffable against
lectio and the raw view does not depend on the parser being correct.
