fix(overlay): claude.md dedicated-tools nudge stops naming tools the host may lack (s01 M1)

The nudge named Glob and Grep, which some Claude hosts do not expose. It now
names the host's dedicated file tools and its search tools when it has them,
keeping the prefer-dedicated-tools behavior the claude-dedicated-tools-vs-bash
overlay eval measures. Updates the prose comment at
test/gen-skill-docs.test.ts:643 (comment only, no assertion change). The
matching comment in test/fixtures/overlay-nudges.ts is left to its owner.
