- 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.
