Add cmd/composure-convert tool that chunks public domain philosophical
texts into training conversation pairs:
- consent.jsonl (198 examples) — Wollstonecraft's Vindication
- privacy.jsonl (221 examples) — Thoreau's Walden
- sovereignty.jsonl (56 examples) — Mill's On Liberty
- transparency.jsonl (159 examples) — Aurelius' Meditations
Each example pairs a domain-specific prompt with ~5 paragraphs from
the source text. Metadata, chapter headings, and Gutenberg boilerplate
are filtered out.
