Memories grow per-flag witness checkboxes (you / host / guest) that
auto-submit on change via HTMX. The new POST route emits a manual_edit
event with target_kind=memory_witness and a {flag, value} payload;
prior_value mirrors the same shape so an inverse edit restores the
flag. The drawer's recent-memories query now selects the three
witness columns alongside the existing fields so the template can
render checkbox state without a second query per row.
Adds the four POST routes whose state-layer support was already
dispatched by the manual_edit projector (edge_trust, edge_summary,
memory_pov_summary) plus a new edge_knowledge_fact dispatch branch for
add/remove fact list manipulation. Drawer template gains editable
textareas, sliders, and add/remove fact controls. Remove semantics on
knowledge_fact match by string (not index) so concurrent edge_update
events appending facts between drawer renders don't desync the form.
