## Summary
- Add stack overflow protection to JSON/JSONC parser to prevent
segmentation faults
- Parser now throws `RangeError: Maximum call stack size exceeded`
instead of crashing
- Fixes DoS vulnerability when parsing deeply nested JSON structures
(~150k+ depth)
## Test plan
- [x] Added regression tests for deeply nested arrays and objects (25k
depth)
- [x] Verified system Bun v1.3.6 crashes with segfault at 150k depth
- [x] Verified fix throws proper error instead of crashing
