feat: add SaaS offers reference to offers skill (discount trap + worked examples)
Adds references/saas-offers.md covering the discount trap (discount-askers
churn ~2x; discount only for upgrades/cross-sells and seasonal, never to
acquire) plus four SaaS worked offers: AudienceTap $297 pilot, SaberSim $497
bundle, Teachable $1,997 accelerator, Kit "Painless Switch" $997 migration.
Wires SKILL.md routing, adds evals.json, bumps offers 1.0.0 -> 1.0.1.
