* Move `DebugThreadLock` to `bun.safety` * Enable in `ci_assert` builds, but store stack traces only in debug builds * Reduce size of struct by making optional field non-optional * Add `initLockedIfNonComptime` as a workaround for not being able to call `initLocked` in comptime contexts * Add `lockOrAssert` method to acquire the lock if unlocked, or else assert that the current thread acquired the lock * Add stack traces to `CriticalSection` and `AllocPtr` in debug builds * Make `MimallocArena.init` infallible * Make `MimallocArena.heap` non-nullable * Rename `RefCount.active_counts` to `raw_count` and provide read-only `get` method * Add `bun.safety.alloc.assertEq` to assert that two allocators are equal (avoiding comparison of undefined `ptr`s) (For internal tracking: fixes STAB-917, STAB-918, STAB-962, STAB-963, STAB-964, STAB-965) --------- Co-authored-by: autofix-ci[bot] <114827586+autofix-ci[bot]@users.noreply.github.com>
