v0.91.0

What's Changed

• docs(changelog): promote 0.91.0
• fix(acp): the catch-up names an unloaded gap even when nothing loaded is new (RMK-159)
• fix(acp): the catch-up says it is partial on a room with no hook (RMK-159)
• refactor(acp): the events mixin declares _sdk as an annotation, like every cross-mixin method
• docs(acp): the channel module names the mixins that carry its mechanics
• refactor(acp): a turn's prompt loop lives in its own mixin
• refactor(acp): room and turn sessions share one module
• fix(acp): a standalone turn session never outlives its turn, and the room's session learns its reply (RMK-223)
• feat(acp): an instruction is the application's direction, and a standalone one runs in a session of its own (RMK-223)
• fix(acp): an instruction moves the catch-up cursor past what it caught up on (RMK-223)
• fix(core): a standalone turn skips the room's working memories, and only the typed field sets it (RMK-223)
• feat(core): a standalone instruction reads nothing of the room, and its reply records a fingerprint (RMK-223)
• Begin 0.91.0.dev0 development
