fix: skip bundled-dep apply prompt when nothing changed; release v1.2.3v1.2.3

After the version-aware reconcile, a --force run on an up-to-date bundle
package still asked "Apply bundled-dep updates?" with nothing to apply.

reconcile_bundle_deps report mode now signals whether there is anything
to apply via its exit code: 2 = changes present, 0 = all current / no
deps / fetch fail. The --check and --hintfile -V callers prompt only on
exit 2. apply mode still returns 0. Adds T-BM24 (all-current → no
prompt); 183 passed.

Bump MKHINT_VERSION and man title to 1.2.3, rebuild mkhint.1.gz.

+- The bundled-dep reconcile no longer prompts `Apply bundled-dep updates?`
+  when nothing changed. Report mode now signals whether there is anything to
+  apply (exit 2 = changes, 0 = all current / no deps / fetch fail), and the
+  `--check` and `--hintfile -V` callers only prompt when there is. Previously a
+  `--force` run on an up-to-date bundle package always asked, with nothing to
+  do.
