Move CLI to separate repo, make this skills-only (Apache 2.0)

The CLI and detection engine now live in pbakaus/impeccable-detect
(published as 'impeccable' on npm, BSL-1.1). This repo is purely
Apache 2.0: skills, prompts, website, and build system.

- Remove bin/ (CLI moved to CLI repo)
- Remove README.npm.md (moved to CLI repo)
- Remove @impeccable/detect dependency, add impeccable dependency
- Set package.json to private (no longer published to npm)
- Update all references from @impeccable/detect to impeccable
- Update CLAUDE.md, NOTICE.md, FAQ, and changelog
- Rebuild all provider skill distributions
