Problem

The feed is requested repeatedly by subscribers' clients and must be cached at the edge like other responses, while still refreshing when the data-version bumps.

Acceptance criteria

The feed sets ETag and immutable cache headers keyed by inputs and data-version.
Conditional requests return 304 when unchanged.
A data-version bump produces a refreshed feed.
Caching behavior is covered by tests.

Notes

Calendar clients poll frequently; correct 304s materially cut origin load.
