Add Part V — Demonology; restructure to 7 parts

Per author's choice, give the PGM/exorcism material (ai_answers.md
Block 2) its own Part, placed before the Battle Manual: theory of the
enemy -> tactics. Add Part V ch01 'The Mechanics of Authority' (one
worldview, name-as-power, adjuration/naming/binding, command-without-
ritual, the 'stronger man'), sourced to NT + PGM, with Christ-authority
and the author's own-methods line left [NEEDS YOUR INPUT].

Renumber empty folders only (battle 5->6, reference 6->7); no existing
content disturbed. Sync design doc, OUTLINE (+Reading Path), CLAUDE.md,
README, STYLE-GUIDE; fix forward refs (Battle now Part VI). All
internal cross-links verified resolving.
