CI: restore pombast cache across smelt runs

ctrueden · claude · ctrueden · commit e333d84af311 · 2026-05-23T08:42:09.000-05:00
Adds restore/delete/save steps for ~/.cache/pombast around the smelt step,
matching the pattern used for the old melting-pot cache.  Cache must be
deleted before re-saving because GitHub Actions does not allow overwriting
an existing cache key.  Both delete and save run unconditionally (if: always())
so the cache is preserved even when smelt has failures.
