fix(k9): add K9! magic line + pedigree block to methodology-guard

The K9 validator (dogfood-gate 'Validate K9 contracts') failed on
methodology-guard.k9.ncl: missing 'K9!' magic number (first non-empty line must be
exactly 'K9!') and missing a 'pedigree = { ... }' section. Add both, matching the
passing must-check / template-kennel validators. Check logic unchanged.
