docs: reconcile examples/README + CLAUDE.md with the heavier reusable default

From PR #10's own review (maintainability/perf lenses): examples/README.md
hadn't been updated for the default swarm, and CLAUDE.md's 'keep the default
model count low' cost guidance read as contradicting the new heavy default.
Clarify that the IMAGE default stays minimal while the REUSABLE ships an
opinionated heavier default consumers inherit/override.
