Wasmtime 36.0.0 aflaai

36.0.0
Released 2025-08-20.

#11228
#11269
#11283
- The async proposal for the Component Model is now fully implemented in
Wasmtime with a number of WASIp3 interfaces implemented. The implementation
is still off-by-default and the implementation of WASIp3 is not fully
complete, but is remains suitable for testing.
