Pull request overview
This PR extracts the unbound list implementation from the type inference library into a new reusable module. The unbound list data structure represents lists as encoded strings and is useful in performance-critical scenarios where a newtype representation is not feasible.
Key Changes:
- Created new shared library
shared/util/codeql/util/UnboundList.qllwith generic unbound list implementation - Refactored
TypePathin type inference to use the new genericUnboundListmodule
