fix(dirvish): declare runtime constant/util deps with plain require

dirvish-config builds `dirvish-quick-access-entries` from `code-dir`, `music-dir`, `pix-dir`, and the recording dirs at load time, and binds keys to `cj/xdg-open` and `cj/open-file-with-command`. Those come from user-constants and system-utils, but the module only required them under `eval-when-compile`, so the compiled module carries no runtime require and leans on init order having loaded them first.

I switched both to plain requires, matching host-environment, system-lib, and external-open-lib right below. Added a dependency-contract smoke test that fails if the requires are dropped.

+;;; Commentary:
+;; dirvish-config.el builds `dirvish-quick-access-entries' from `code-dir',
+;; `music-dir', `pix-dir' (and friends) at load time and binds keys to
+;; `cj/xdg-open' / `cj/open-file-with-command', so it depends on user-constants
+;; and system-utils at runtime.  Those were declared with `eval-when-compile',
+;; which leaves the compiled module without the requires at load — fragile
+;; under init order.  This is a dependency-contract smoke test: requiring
+;; dirvish-config in isolation must pull both features in, so it fails if the
+;; requires are dropped entirely.  (It can't catch a downgrade back to
+;; `eval-when-compile', since that form still runs when the file loads as
+;; source, which the test harness does — that regression is guarded by keeping
+;; the plain requires in review, not by this test.)
