The modern route helpers normalize `{ channel, to, accountId, threadId }`

consistently across native approvals, reply suppression, inbound dedupe,

cron delivery, and session routing. If your plugin owns custom target

grammar, use `resolveChannelRouteTargetWithParser(...)` to adapt that

parser into the same route target contract.

cron delivery, and session routing.

Do not add new uses of `ChannelMessagingAdapter.parseExplicitTarget` or

the parser-backed loaded-route helpers (`parseExplicitTargetForLoadedChannel`

or `resolveRouteTargetForLoadedChannel`) or

`resolveChannelRouteTargetWithParser(...)` from `plugin-sdk/channel-route`.

Those hooks are deprecated and remain only for older plugins during the

migration window. New channel plugins should use

`messaging.targetResolver.resolveTarget(...)` for target id normalization

and directory-miss fallback, `messaging.inferTargetChatType(...)` when core

needs an early peer kind, and `messaging.resolveOutboundSessionRoute(...)`

for provider-native session and thread identity.
