0.7.6

What's Changed

This release fixes allocator correctness issues in overflow handling, remote deallocation, and Windows process teardown. It also improves concurrent queue draining, adds RISC-V timing support, prepares the Rust crates for 0.7.6, fixes Rust build configuration and header-only integration documentation, and refreshes CI and contributor guidance.

• Initialize PalTimer link state for non-static timers by @devnexen in #865
• Preserve batched remote deallocations with pointer-domesticating configurations by @sblessing in #877
• Prevent Windows process-shutdown crashes by retaining VirtualVector reservations, while continuing to release them when a DLL is explicitly unloaded with FreeLibrary, by @mjp41 with @Copilot in #886
