chore: upgrade zig to 0.14.0

[190n]

Major causes of changes:

• std.mem.Allocator vtable changed (alignment is an enum instead of a u8; remap function added)
• std.ArrayList.pop changed to return an optional, and std.ArrayList.popOrNull deleted
• runtime page size
• minor zig fmt changes
• std.ArrayList initial capacity changed (the places that broke have been changed to not rely on the capacity)
