* fix(subscriptions): preserve older-host workflows and explicit timeline recovery
Keep established app and SDK workflows available on older daemons without emulating independent directory filters. Restore live timeline membership without choosing the consumer's history recovery policy. Preserve daemon filesystem paths separately from legacy workspace IDs.
* fix(client): keep legacy workspace replies scoped to the requested page
Give each observation a server-issued ID owned by its physical connection. Preserve snapshot-only reads and combined list-and-subscribe, source-bound replies, lifecycle cleanup and legacy wire compatibility.
Move supported protocol capabilities into client defaults and make session traffic subscription-driven. Preserve timeline readiness and reconnect recovery across SDK, CLI, and plugin consumers.
