Expose a toDevShell function on every mkDerivation output that converts the derivation into a development shell, preserving its build environment (compiler, flags, phases, environment variables). Accepts either an attrset or a function (stdenv -> attrset) for conditional inputs. See: ekala-project/eeps#1
Rewire toDevShell passthru so that drv.toDevShell {} calls mkDevShell
under the hood, giving every derivation access to ekaos service modules,
language modules, and process-compose integration in its dev shell.
mkDevShell gains nativeBuildInputs, propagatedBuildInputs,
propagatedNativeBuildInputs, inputsFrom, env, and name parameters so it
can receive the full build environment from toDevShell.
to-dev-shell.nix now produces a mkDevShell-compatible attrset, merging
the original derivation's dependencies and extracting env vars while
filtering out phase hooks and build infrastructure attrs.
mkDevShell is injected lazily into config so make-derivation.nix can
reference it without circular evaluation.
