Remove Swatinem/rust-cache from all workflows and standardize on sccache as the sole compilation cache. sccache caches individual compilation units via the GHA cache API, which works both on host runners and inside Docker/manylinux containers — unlike Swatinem which only caches host-level target/ directories. Changes: - Remove Swatinem/rust-cache from build-runtime, build-wheels, build-node, and test workflows - Extend sccache to macOS (previously Linux-only) by removing platform conditions from sccache setup and GHA env export steps - Add sccache to clippy (lint.yml) and cli/go test jobs (test.yml) - Skip sccache for rust test job (cargo-llvm-cov conflicts via RUSTC_WRAPPER) - Add CARGO_INCREMENTAL=0 everywhere (required for sccache) - Chain build-runtime after warm-caches via workflow_run trigger - Fix build-wheels Export step: remove explicit SCCACHE_GHA_ENABLED and RUSTC_WRAPPER (let sccache-action set them on success only) - Update README.md with new architecture diagram and cache docs
Unify CI workflows around sccache with GHA cache API variables and align warm-caches/build-runtime orchestration so cache warmup is reflected consistently in workflow behavior and docs.
