Author Common-of-a-Dedication Lauds psalmody, closing 10/10 sweep

Live-verified the real scheme against Divinum Officium (Monastic
Tridentinum 1617, votive=C8) across all 7 weekdays: proper antiphons on
Ps 50/5/35, plus a canticle slot whose antiphon is fixed to this Common
but whose underlying text follows the plain ferial weekday rotation
(all 7 already authored). Required making
LaudsPsalmodyOverride.canticle.id optional and having resolvePsalmody
splice in the day's own ferial canticle when a category omits it.

+# Generic Common-of-a-Dedication (of a Church) Lauds psalmody, live-
+# verified against Divinum Officium (Monastic Tridentinum 1617, command=
+# prayLaudes, votive=C8, 2026-09-05 — all 7 weekdays checked, 11-09 through
+# 11-15-2026). Genuinely its own scheme, unlike most Commons: proper psalms
+# 50/5/35 (not the usual 92/99/62), same "own numbers, not the standard
+# duplex-majus set" pattern already noted in this Common's own Vespers file
+# (109/110/111/147).
+#
+# The canticle slot is unusual again, in a different way: its *antiphon* is
+# this Common's own fixed text ("Bene fundáta est...", confirmed identical
+# on every weekday tested), but the underlying canticle *text* is not
+# proper to Dedication at all -- it's simply whichever plain ferial
+# weekday canticle the day already uses (Isaiah Mon, Ezechias Tue, Anna
+# Wed, Moses/Exodus Thu, Habacuc Fri, Moses/Deuteronomy split Sat, Three
+# Young Men Sun) -- all 7 already authored, hours/lauds-canticles.ts. This
+# supersedes the earlier (2026-08-28) note on this file's Vespers sibling
+# claiming a "Canticum Ieremiæ" was needed and never transcribed -- that
+# was a live-verify session that captured a plain ferial Thursday's output
+# instead of actually passing votive=C8; no such canticle appears anywhere
+# in the real Dedication scheme on any weekday. `canticle.id` is
+# intentionally omitted here -- see hours/lauds.ts's resolvePsalmody and
+# hours/lauds-psalmody-overrides.ts's own doc comment for the fallback.
