Add Lobsters CLI

Goal

Add a Printing Press CLI for Lobsters, focused on high-signal developer community monitoring.

Free source

• Lobsters public site and RSS feeds.

Agent jobs

• Check the current front page without browser scraping in every agent session.
• Search recent stories/comments around a technical topic.
• Track topic pulse over time.
• Compare Lobsters discussion against Hacker News when both cover the same URL/topic.

Proposed command shape

• lobsters-pp-cli stories frontpage --agent
• lobsters-pp-cli stories newest --agent
• lobsters-pp-cli search "sqlite" --days 30 --agent
• lobsters-pp-cli comments <story> --agent
• lobsters-pp-cli pulse "rust" --days 30 --agent
• lobsters-pp-cli sync && lobsters-pp-cli since --agent

Non-goals

No posting, voting, commenting, private messages, or account mutation.\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.
