feat(P01): render PPTX + CAP-042 + D-241 record + frontmatter-comment fix

- render_pptx.py: skip leading HTML comments before frontmatter (split_slides + parse_frontmatter)
- docs/presentations/nova-leadership-deck.pptx: 7 slides, footer on every slide
- STATE.md: CAP-042 row appended (leadership deck, single-shot, Aug 2026)
- PROJECT.md: D-241 formal entry (single-shot, discrete, no compression)
- smoke test exits 0 (all 6 assertions a-f pass)
