Add FEC campaign finance CLI

Goal

Add a Printing Press CLI for campaign finance research.

Free source

• FEC API with free API key.

Agent jobs

• Research candidates, committees, filings, donors, and money flows.
• Summarize contribution patterns for public-interest or market research.
• Monitor newly filed reports.

Proposed command shape

• fec-pp-cli candidate <name-or-id> --agent
• fec-pp-cli committee <id> --agent
• fec-pp-cli filings --candidate <id> --agent
• fec-pp-cli donors --committee <id> --agent
• fec-pp-cli money-flow --race <id> --agent

Non-goals

No donor targeting, harassment workflows, or political advice.\n\n## Implementation path\n\nThis is a new CLI candidate, so do not hand-build it directly in this published library repo. Run it through the canonical Printing Press generation flow in cli-printing-press, keep manuscripts/proofs, then publish into this repo with the publish flow.\n\n## Acceptance criteria\n\n- Research notes explain the source/API/feed contract, rate limits, auth needs, and freshness behavior.\n- CLI exposes a small agent-native command set, not a raw endpoint dump.\n- --json / --agent output is stable and compact.\n- If the source benefits from history, add local SQLite sync plus since/diff commands.\n- Skill includes high-signal recipes and clear non-goals.\n- Dogfood proves at least three realistic agent workflows.
