Alias Virgin/Confessor-Doctor/Confessor-Pope to existing Matins Common schemes

Read the reference engine's CommuneM/*.txt templates directly (C6a,
C4a, C4b), rather than trial-and-error live queries, to confirm each
whole-file-inherits its parent Common's Matins nocturn psalmody with no
override. Live-verified byte-identical against St. Scholastica (Virgin
-> Virgin-Martyr) and St. Ambrose (Confessor-Doctor -> Confessor-Bishop);
Confessor-Pope -> Confessor-Bishop aliased on the source redirect chain
alone, since none of vu's three Pope-Confessor saints exist on the
Monastic-1617 calendar at all (matching the convention their own files
already use for every other hour).

+#
+# - Confessor-Doctor (`C4a`): `CommuneM/C4a.txt` whole-file inherits
+#   `@CommuneM/C4` (this file) with no `[AntMatutinumM]`/`[Ant
+#   Matutinum]`/versicle override anywhere -- its own `[Ant 1]`/`[Ant 3]`
+#   blocks are Lauds antiphon tags (same bare naming as `Commune/C4.txt`'s
+#   own `[Ant 3]`/`[Ant 3 summi Pontificis]` pair, confirmed Lauds-only by
+#   cross-reference), not Matins Nocturn 3. Live-verified against St.
+#   Ambrose (2026-12-07, `vide C4a`, real Duplex day): every antiphon,
+#   psalm number, AND all three versicles (`Amávit eum Dóminus...` /
+#   `Elégit eum Dóminus sacerdótem sibi...` / `Tu es sacérdos in
+#   ætérnum...`) reproduce this file exactly. Independently corroborated
+#   by St. Basil the Great's own case above (also `vide C4a`, also
+#   byte-identical) -- two saints, same finding.
+# - Confessor-Pope (`C4b`): `CommuneM/C4b.txt` whole-file inherits
+#   `@CommuneM/C4` and only overrides Oratio variants, Lectio9-12
+#   (redirected to `@SanctiM/03-12`, St. Gregory the Great's own
+#   lessons -- irrelevant to this psalmody-only module), and a Lauds
+#   `[Ant 3]` cross-reference into secular `Commune/C4:Ant 3 summi
+#   Pontificis` -- again no Matins-nocturn-psalmody override at all.
+#   Not live-verifiable against a real Monastic-calendar saint: all
+#   three vu saints carrying this Common (`st-leo-ii`, `st-pius-v`,
+#   `st-pius-x`) turn out to have no `SanctiM/*.txt` file at all -- none
+#   of them are observed under the Monastic-1617 track vu's structure
+#   otherwise follows, only under the secular/Divino-Afflatu tracks vu's
+#   calendar also draws from (per this repo's own CLAUDE.md). Aliased on
+#   the strength of the source redirect chain alone, consistent with the
+#   convention already established in all three of those saints' own
+#   files, which already fall back to this same Common for their
+#   Benedictus/minor-hours content for the identical reason (no
+#   Pope-specific content exists to fall back to instead).
