  close perf: hoist get_failure_schema symbols to compile-time constants #45

[usmanimamu17-create]

Thanks for the cleanup @nelly439! Before merging, can you double-check the closing issue? Your PR body references close #45, but issue #45 is about a Rust performance optimization — hoisting get_failure_schema symbols to compile-time constants in apexchainx_calculator/src/lib.rs. This PR only touches TypeScript files (tests/thresholdEdgeCases.test.ts + new types/jest-globals.d.ts), so the link doesn't line up with the changes. Could you update the PR description to point at the right issue, or open a new one describing the TypeScript fix so the close-reference matches the work? Once that's clarified I'll happily merge.

Thanks for cleaning up the TypeScript errors, @nelly439! Tests behave now and the new jest globals shim is a nice touch. Merging. ✅
