Jade Ellis	db50adc000	feat: Add bundled aggregations support Add support for the m.replace and m.reference bundled aggregations. This should fix plenty of subtle client issues. Threads are not included in the new code as they have historically been written to the database. Replacing the old system would result in issues when switching away from continuwuity, so saved for later. Some TODOs have been left re event visibility and ignored users. These should be OK for now, though.	2025-06-14 19:40:26 +01:00
