 * Durable, mutable per-conversation GitHub channel state, persisted as JSON.
 *
 * Which fields are populated depends on `conversationKind`: `review_thread`
 * state sets `reviewCommentId`/`reviewThreadRootCommentId`, issue and PR
 * timeline comments set `triggeringCommentId`, and issue/PR conversations set
 * `issueNumber`/`pullRequestNumber`. See the `stateFrom*` builders for the
 * exact mapping per kind.
 *
 * The checkout-derived fields (`checkoutPath`, `headSha`, `baseRef`) start
 * null. The default `turn.started` handler fills them in once it checks out
 * the repository, which is why the fields are mutable.
