refactor: narrow pub(crate) items to private

Porting mapped every PHP `protected` member onto `pub(crate)`, which is
wider than nearly all of them need. Each item demoted here is reached
only from the module that defines it, so the crate-wide visibility
conveyed nothing.

Every `pub(crate)` that survives has at least one reader in another
module of the same crate.
