nixception 0.4.0

This release makes nixception usable outside a build sandbox and adds a real
integration test suite around that.

Highlights

  • Isolated store support. NIXCEPTION_STORE_ROOT (or the store_root
    config field) relocates the server's store reads to <root>/nix/store/..., so
    nixception can run against an isolated Nix daemon whose physical store lives
    outside the real /nix/store. Paths on the wire and in derivations stay
    logical; it's off by default and inert when unset.

  • Standalone integration tests. A new Rust suite spins up a throwaway chroot
    store + isolated daemon, points a standalone nixception at it, drives recc
    compiles, and asserts on the resulting store (a compile lands as a
    -reapi-action path, distinct compiles differ, an identical re-compile is a
    cache hit). This exercises the non-sandbox path and enables store-level
    assertions the derivation-based checks can't. Run with just test-standalone.

  • Quieter builds by default. The recurring nixception-hook: mem … cgroup
    memory sampler is now off by default (set NIXCEPTION_DEBUG_MEM=1 to
    re-enable); the on-failure OOM report still runs.

See the changelog for the full list.
