feat(tokens): compress the 10 fattest personal skill descriptions

6,416 → 4,243 chars (≈ −540 tokens/session, catalog loaded every
session). Kept per BDR-014/LRN-043: 'Use when' pattern, discriminating
FR+EN triggers, all 'For X → /Y' disambiguation lines. Cut: redundant
trigger synonyms, header/engine enumerations, prose the model derives.
find-docs excluded (ctx7-owned, regen clobbers — LRN-086); doc + geo
taken instead. All ≤ ~505 chars body (BDR-014 aspirational ceiling).
