arc-1e68f1[bot] 70ea9f458d Add goal to WorkflowRunStarted and render in fabro logs --pretty (#6)
This PR adds a `goal` field to the `WorkflowRunStarted` event so that
users can immediately see what a workflow is trying to accomplish when
reading logs. The field is an `Option<String>` with `serde(default,
skip_serializing_if)` to maintain backward compatibility with existing
JSONL logs that don't include it—mirroring the same pattern used by
`base_sha` and `run_branch`.

On the rendering side, `fabro logs --pretty` now displays the goal below
the workflow header line when present, using markdown rendering with
proper indentation and terminal-width wrapping. The markdown rendering
logic was extracted into a shared `render_indented_markdown` helper,
which is also now used by the existing `AssistantMessage` rendering to
eliminate duplication.

Tests cover round-trip serialization with a goal, backward-compatible
deserialization of old events without the field, verification that
`None` goals are omitted from JSON output, and pretty-formatting
behavior both with and without a goal present.
