Add AgentAd ad schemas as a LogicSRC primitive (#10)

* Add AgentAd ad schemas as a LogicSRC primitive

AgentAd is a disclosed, agent-readable advertising contract for CLI tools
and AI agents. LogicSRC owns the canonical schemas; cl1s.tech is the
reference network built on them.

- packages/schemas: agentad-{ad,placement,ad-request,ad-response,
  impression,click,campaign} schemas (id under schemas.logicsrc.com) +
  ad/placement fixtures, exported from @logicsrc/schemas
- packages/validators: register the 7 agentad kinds, wire fixture
  validation, add tests (disclosure.sponsored must be true)
- docs/agentad.md: the AgentAd spec
- README: list AgentAd under v1 priorities

Validators build clean; all fixtures validate; vitest 4/4 green.

* Prepare @logicsrc/schemas for npm publish

Add license, repository, homepage, keywords, publishConfig (public),
and a package README covering both the logicsrc-* core schemas and the
agentad-* family.
