- Memory Insights: Added analysis support for "free callstack" for an allocation (i.e. callstack when an allocation if freed).
- Memory Insights: Switched CallstackId to 32 bit and moved the resolving of "id to pointer" outside of mem queries. This allows us to add the second callstack id and also ids for future metadata without increasing the size of FAllocationItem struct (from AllocationProvider).
- Memory Insights: Refactored code re ThreadId and Tracker passed from AllocationAnalysis to AllocationProvider.
- Memory Insights: Refactored code re CallstackProvider to map a CallstackId directly as an index into array of callstacks.

- Memory: Added a new query rule: **Growth vs. Decline**. Identifies \"growth\" allocations, allocated between time A and time B and freed after time B (A ? a ? B ? f) and \"decline\" allocations, allocated before time A and freed between time A and time B (a ? A ? f ? B). The \"decline\" allocations are changed to have negative size, so the size aggregation shows variation between A and B.
- Memory: Fixed the iteration over SBIF offsetted cells resulting in some cells to be skipped when checked by queries.

- Memory: Improved speed of live allocs matching in memory analysis.
- Memory: Fixed N/A callstacks in a query made before analysis is completed.

- Memory: Added two new query rules: "Free Events" and "Alloc Events".
- Memory: Fixed tooltip for query rules in the dropdown list not showing the name of markers.
- Memory: Fixed margins around "target window".
- Memory: Simplified status text with query rule info in Allocs Tree view.

Code that resolved callstacks from owner id was missing from "live allocations" set, causing many N/A callstacks in memory queries.

- Implemented mem alloc queries also for live allocs.
- Implemented analysis for llm tags associated with allocations (based on initial work by Johan.Berg).
- Changed granularity of memory allocations timelines to 0.1ms (from 1ms).
- Fixed allotment of allocations in SbTree's offsetted cells.
- Fixed queries to handle also cases where multiple cells have exact same timestamps.
- Added more debug/validation code for AllocationsProvider.

- Added detection for AllocationsProvider availability to know when to enable the Memory Insights tab (in addition to detecting availability of the LLM tags memory provider).
- Simplified the API for allocation queries (using A, B, C, D time markers).
- Added initial AllocationsAnalysis that processes the allocation trace events and delegates them to AllocationsProvider.
- Added initial AllocationsProvider. Uses a simple map for live allocations.
- Added FSbTree ("SBIF with offsetted cells" data structure for storing the retired allocations in AllocationsProvider).
- Added async allocation queries (based on A, B, C, D time markers). Currently it uses a single TaskGraph task.
- Added "LogTraceServices" log category for general purpose logging in TraceServices module.
