Seasonal Intelligence: restructure into A Day's Walk + Seasonal Intelligence

Theory revised and narrowed to what the evidence supports; renamed The
Relevance Theory. Project split into two books and six essays, with the
three-tier relevance model promoted to the flagship.

- EVIDENCE.md   claims sorted into four tiers, governs what may be claimed
- CRAFT.md      lyric/landscape register, governs how it may be said
- PORTFOLIO.md  the two-book plus six-essay split, and what was cut
- BOOK_ONE_CHAPTERS.md  walk spine on the Stezka Ceskou Kanadou,
                        beats for all 14 units, argument ledger
- FIELD_BRIEF.md        what to capture on the trail
- drafts/       prologue, ch 3, ch 5 (register tests, specifics are placeholders)
- archive/      original theory and outline, unchanged

Cut: the foreign-policy argument, the weight-loss protocol, the diagnostic
scoring, the I/me labels, the seasonal network mapping (demoted to metaphor
in Book Two).
