Tak Hoffman f94d6778b1 fix(active-memory): Move active memory recall into the hidden prompt prefix (#66144)
* move active memory into prompt prefix

* document active memory prompt prefix

* strip active memory prefixes from recall history

* harden active memory prompt prefix handling

* hide active memory prefix in leading history views

* strip hidden memory blocks after prompt merges

* preserve user turns in memory recall cleanup
