Add CLI Usage Examples with Mission Alignment to README

[github-actions[bot]]

Description

The top-level README currently outlines the repository's purpose and features, but it is missing concrete CLI Usage examples that demonstrate how each supported flag contributes to our mission: Build a knowledge graph of the physical world by crawling public data sources. Adding this section will help new contributors and users quickly understand and verify the CLI capabilities in practice.

Proposed Changes

1. Add a ## CLI Usage section below Getting Started in README.md.
2. List each supported flag (--help, --version, --mission, --ingest <url>, --ingest-all <url>) with:
   • A brief description of its purpose.
   • A code block showing the example command and its expected output.
3. Align each example with the mission by explaining how it supports building, inspecting, or persisting the knowledge graph.
4. Optional: Merge or replace any existing "Running the Demo" section with these updated examples.

Acceptance Criteria

• [ ] README.md contains a ## CLI Usage heading at the correct location.
• [ ] Each CLI flag has at least one example command in a fenced code block.
• [ ] The output shown in each example matches the actual output produced by running the command locally.
• [ ] Each example includes a one-sentence note tying it back to the mission (e.g., fetching data, persisting records, inspecting graph state).
• [ ] Manual smoke tests have been executed for all examples to confirm correctness.

No code changes or tests are required for this documentation update.
