Martin Vogel 7814dacf15 fix: size the compress path with size_t and prune the cache from the walk
Two loose ends from the bounds work.

The decompression side already took size_t so a >2 GiB capacity could not wrap
through int, but compression still took int for both the source length and the
destination capacity, and the artifact export cast a size_t database size down
to reach it. A database past 2 GiB would have handed the encoder a negative
length. Both lengths and the bound helper are size_t now, and the function
returns int64_t like its decompressing counterpart.

The discovery walk now prunes the cache directory by absolute path. A custom
CBM_CACHE_DIR may sit inside a repository — tests do it routinely — and walking
into it pulls every other project's graph database into this project's file
list. This is the narrow form of a concern that was briefly implemented as
refusing any root that contained the cache; refusing a whole root was too blunt,
and not walking the cache is what the concern actually asks for.

The test fails without the prune: a .go file planted under the cache is
otherwise discovered, and "cache" is not in the built-in skip list, so the
assertion is not vacuous.
