fix(archiver): resolve infinite recursion in exclude filter dispatch

The Phase B port invented an ArchivableFilesFilter trait whose filter
impls called self.filter, recursing forever; the name also collided
with the real ArchivableFilesFilter FilterIterator class. Composer has
no such interface: the finder holds GitExcludeFilter/ComposerExcludeFilter
(both extending BaseExcludeFilter) and calls $filter->filter().

Drop the invented trait, type the filters as Box<dyn BaseExcludeFilter>,
and implement BaseExcludeFilter on the concrete filters (accessors
delegating to inner). Remove the unused generic default methods from the
trait so it is dyn-compatible; they remain as inherent methods on
BaseExcludeFilterBase, which is where every caller already reaches them.
