chore: release 4.2.2 (#534)

Merge main into release to publish 4.2.2.

## Changes in 4.2.2

### Fixed

- **All languages:** `CalendarEventsResponse` now exposes `next_date`
cursor — callers can pass it as `start` (with the same `end`) to fetch
the next page of `/v1/quote/finance_calendar` results
- **All languages:** `CalendarEventInfo.symbol` now returns standard
symbol format (e.g. `CRM.US`) instead of raw `counter_id` format (e.g.
`ST/US/CRM`)
