Get a manufacturer product timeline

- object
  - `success` boolean, required: Always true on a successful response. Every error carries `false` and an `error` object instead.
  - `data` object, required: The response payload.
    - `manufacturer` object: Who the timeline is for.
      - `id` string: Slug of the manufacturer.
      - `name` string: Display name, as the maker writes it.
    - `timeline` object[]: One entry per year they introduced something, oldest first.
      - `year` integer, nullable: Year of introduction. Null groups the firearms whose year is unrecorded.
      - `firearms` object[]: The firearms they introduced that year.
        - `id` string: Slug of the firearm.
        - `name` string: Display name, as the maker writes it.
        - `yearIntroduced` integer, nullable: Year it entered production or service. Null where the date is disputed or unknown.
        - `categoryId` string, nullable: Slug of the category it belongs to. Resolve against `/v1/categories`.
        - `status` string, nullable: Production status, one of `in_production`, `discontinued`, `out_of_production`, `in_service`, `limited_production`, `prototype`. Discontinued records are kept deliberately: a rifle built in 2004 wears parts nobody sells today.

## Other responses

- `400`: Validation error
- `401`: Missing or invalid API key
- `403`: The credential is valid and the caller is not permitted. Three causes, none of which reissuing a key changes: the plan is below the endpoint's tier, the account is suspended, or the key is not attached to the thing being acted on, meaning a user account for `/v1/me` or a shop for `/v1/vendor`. Distinct from 401, which means the credential is missing, malformed or expired and a new one can work.
- `404`: Resource not found
- `429`: A limit was reached. `RATE_LIMITED` is the per-minute limit: wait `Retry-After` seconds (a minute) and retry. `DAILY_CAP_EXCEEDED` is the plan's daily limit, per key: nothing will be served until the counters return to zero at midnight UTC. `MONTHLY_CAP_EXCEEDED` is the plan's monthly allowance, for the whole account: nothing will be served until midnight UTC on the first of next month, or until the plan changes. For both, `Retry-After` is the seconds until then and `error.resetsAt` says when as an instant. Calls made after a refusal are refused too and do not spend the month, and a free key that keeps calling is paused, so stop at the first one and resume at the reset.
- `500`: Internal server error
