Subject: [PATCH] ci: remove SCCACHE_GHA_ENABLED to stop cache entry explosion

The sccache GHA backend stores one cache entry per compiled artifact,
creating ~1000 tiny entries that evict the much more valuable
Swatinem/rust-cache entries (full target/ snapshots) via LRU.

Remove SCCACHE_GHA_ENABLED from all workflows. On hosted runners
sccache falls back to local disk (harmless no-op on ephemeral VMs).
On the self-hosted GPU runner it continues to work via persistent
local disk cache. The other optimizations from #372 (shared-key,
save-if, cache-on-failure, RUSTC_WRAPPER) remain in place.
