 * Main entrypoint for Claude Code Agent SDK types.
 * This file re-exports the public SDK API from:
 * - sdk/coreTypes.ts - Common serializable types (messages, configs)
 * - sdk/runtimeTypes.ts - Non-serializable types (callbacks, interfaces)
 * SDK builders who need control protocol types should import from
 * sdk/controlTypes.ts directly.

// Re-export settings types (generated from settings JSON schema)

 * Forked sessions start without undo history (file-history snapshots are not

 * @param options - `{ dir?, upToMessageId?, title? }`

 * session in the same dir won't double-fire. Releases the lock and closes
 * the file watcher when the signal aborts.
 * - `fire` — a task whose cron schedule was met. One-shot tasks are already

 *   (or deleted if aged out).
 * - `missed` — one-shot tasks whose window passed while the daemon was down.
 *   Yielded once on initial load; a background delete removes them from the
 *   file shortly after.
 * Intended for daemon architectures that own the scheduler externally and
 * spawn the agent via `query()`; the agent subprocess (`-p` mode) does not
 * run its own scheduler.

 * Hold a claude.ai remote-control bridge connection from a daemon process.
 * The daemon owns the WebSocket in the PARENT process — if the agent
 * subprocess (spawned via `query()`) crashes, the daemon respawns it while
 * claude.ai keeps the same session. Contrast with `query.enableRemoteControl`
 * which puts the WS in the CHILD process (dies with the agent).
 * Pipe `query()` yields through `write()` + `sendResult()`. Read
 * `inboundPrompts()` (user typed on claude.ai) into `query()`'s input
 * stream. Handle `controlRequests()` locally (interrupt → abort, set_model
 * → reconfigure).
 * Skips the `tengu_ccr_bridge` gate and policy-limits check — @internal
 * caller is pre-entitled. OAuth is still required (env var or keychain).
 * Returns null on no-OAuth or registration failure.
