* docs(channels): scope implicitMentions overrides to the channels that read them
Only Mattermost, Slack, and Tlon call resolveChannelImplicitMentions, and they
are the only channels whose schemas accept the key. The other documented
producers pass no policy, so allowedImplicitMentionKinds stays undefined and
every produced fact counts as a mention.
* docs(channels): correct implicitMentions override wording
QQBot is a listed reply-to-bot producer with a passthrough schema, so the key
is accepted and ignored there rather than rejected. Also drops 'yet', which
implied a planned rollout while #80234 is still an open product decision.
* docs: limit implicit mention claims to bundled channels
