feat(genomic): add skills field to BoilerplateConfig

Add BoilerplateSkill interface and optional skills[] field to the base
BoilerplateConfig type, enabling any CLI built on genomic to declare
agent skills for post-scaffold installation via the agentskills.io CLI.

Callers read result.config.skills after scaffold/inspect and handle
the actual npx skills add invocations themselves.
