fix(cbtree-test): ensure proper alignment of `version_` in `NodeBase` on ARM64
In the `TestCBTree.TestLeafNode` test case, a SIGBUS error occurs on ARM64
when accessing the `version_` field in the `NodeBase` structure. This is
due to the `PACKED` attribute causing misalignment of the `version_` field,
which is a `uint64_t`. On ARM64, unaligned access to 8-byte data triggers
a SIGBUS, whereas x86 platforms can handle such accesses without crashing.
This commit fixes the issue by ensuring proper alignment of the `version_`
field, preventing the SIGBUS error on ARM64 platforms.
