Log movies and episodes as watched, with the date of the watch.

Trakt API: https://cotlet.dev/docs/api/trakt.md

`POST https://cotlet.dev/api/v1/trakt/histories`

Access: write.

Adds plays to your history. A show with no seasons logs every episode, so name seasons and episodes when you mean a few. A watched_at in the past is accepted. Trakt does not check for duplicate plays, so use get_history first. It reaches no one and remove_from_history undoes it, so it needs no confirmation.

## Parameters

| Name | Type | Required | Description |
|---|---|---|---|
| `items` | array | yes | Titles to change. Each item is an object: type ('movie', 'show', 'season' or 'episode'), title and year, or trakt_id from search_titles. Seasons and episodes also take season and episode numbers. add_to_history also takes watched_at, rate_titles takes rating. |
