fix(tvix/castore): handle Directory::size overflow explicitly r/6777
We use checked arithmetic for computing the total size, and verify
that size is in-bounds in Directory::validate.

If an out-of-bounds size makes it to the "unchecked" size method,
we either panic (in debug mode), or silently saturate to u32::MAX.

No new panic sites are added, since overflows in debug mode already
panic at the language level.
