The counting implementation is unchanged; this changes what /buzz/v1 takes
and returns so later upgrades land in place.
- Sidebar rows are { channel_id, unread, mentions, read_through_id,
latest_id, threads }; thread rows are { root_id, unread, mentions,
read_through_id, latest_id }. Channel unread/mentions count top-level
messages only, and the channel latest_id is the last top-level message
(never a reply or an unresolved reply), so a channel mark_through can
always use it. Exactness (exact/at_least/unknown), channel metadata and
`account` are no longer on the wire.
- POST /me/read-state returns the updated rows of the channels it applied
to. mark_channel_read and the explicit-contexts read are removed.
- Migration 0058 records each frontier's anchor message id (reported as
read_through_id) and drops the whole-channel threads cut.
