Bake sccache into the SDK image and enable it via RUSTC_WRAPPER in CI and the devcontainer (not repo-wide, so non-SDK builds are unaffected). - container/Containerfile: install the sccache musl binary. - ci.yml: RUSTC_WRAPPER=sccache, CARGO_INCREMENTAL=0, SCCACHE_DIR=/sccache, cache size cap, plus a `sccache --show-stats` step per job. - runner-config.example.yaml: bind-mount /var/cache/sccache into job containers so the cache persists across runs and is shared between jobs. - .devcontainer: enable sccache with a named cache volume.
