Module types 

Typed model of the Copilot CLI events.jsonl stream.

⚠️ The events.jsonl schema is undocumented and reverse-engineered. See docs/agents/formats/copilot-cli/events.md. Everything here is built to be tolerant: the line envelope accepts the payload inline, under data, or under payload; field extraction tries several key spellings; unrecognized event types fall through to CopilotEvent::Unknown so a schema change degrades gracefully instead of dropping data.

When a real session is captured (see docs/agents/formats/copilot-cli/known-gaps-and-sourcing.md), tighten the extraction here against the observed shapes and upgrade the confidence tags in the docs.
