Remove Azure AI Search (notes search) feature

- Delete notes CLI and Azure Search client implementations
- Remove AZURE_SEARCH_* env vars and embedding constants from config and .env.example
- Update config to stop validating/creating Azure Search client
- Strip notes references from README, SETUP_CHECKLIST, and GitHub Copilot instructions
- Remove notes subcommand from main CLI and adjust help text
- Remove azure-search-documents dependency from pyproject and prune lockfile
- Update tests to stop setting AZURE_SEARCH_* and tweak sample content accordingly
