Complete rewrite of README.md to document the default rust-workflow
behavior, all installed tools (organized by category), the full cache
strategy (BuildKit mounts + runtime volumes + sccache), cross-compile
targets and tooling, miri usage, environment variables, and docker-compose
example with all volumes wired up.
- README.md: add default-workflow quickstart; add tool tables for linting,
formatting, testing, coverage, benchmarking, profiling, fuzzing,
debugging, inspection, build/release, cross-compile, WASM, docs, and
dev-loop categories; add cache section covering BuildKit --mount cache
IDs, named volumes, host bind mounts, sccache activation and remote
backends; add cross-compile section with pure-Rust/zigbuild/cross usage
and caveats table; add miri section; update env vars table with
SCCACHE_DIR, CARGO_INCREMENTAL, RUSTC_WRAPPER, CARGO_WORKDIR,
CARGO_BUILD_TARGET; update docker run and docker-compose examples to
include all three volumes
README.md
Aligns README install/run snippets with the new convention split:
rootfs/ for Dockerfile-build content (image filesystem), volumes/
for docker-compose host bind-mounts. Compose mounts, host bind
paths, and runtime data dirs are renamed; Dockerfile COPY/ADD
sources (where present) are preserved.
