PR Summary
Major refactoring of the HogVM implementation in Rust, adding JSONExtract functionality and changing error handling behavior for unknown globals.
- Added
construct_free_standing
function inrust/common/hogvm/src/values.rs
to create HogValues from JSON without VM heap access - Modified native function system in
rust/common/hogvm/src/context.rs
to improve heap allocation handling through the newwalk_emplacing
utility - Changed unknown global variable handling in
rust/common/hogvm/src/vm.rs
to return Null instead of errors for more flexible runtime behavior - Added JSONExtract to
RUST_HOGVM_STL
array inposthog/models/error_tracking/hogvm_stl.py
for parsing nested JSON values

Also makes unknown globals be treated as Null's, rather than returning an error.
The easiest way to tell that this does what it's supposed to is by looking at the test programs, for reviewers
