Re-verify session's rhythm fixes against fetched public-domain scores

Browse Source 
Went back through the pieces modified this session and checked each
against an actual fetched source (mobilehymns.org, gmajormusictheory.org
public-domain hymnal/beginner scores, rendered and read directly) instead
of relying on memory alone. Corrected what didn't match:

- Oh! Susanna: chorus was too fast/rhythmically flat; the real setting
  opens "Oh! Su-" on sustained half notes, much slower than the verse
- Camptown Races: "Doo-dah! Doo-dah!" was an even stepwise run; the real
  song is quick "Doo-" + long held "dah!" (quarter + dotted-half)
- We Three Kings: refrain confirmed to be in a lilting compound meter,
  not straight 4/4 as this had it; opening "O" adjusted toward that feel
- Angels We Have Heard on High: the Gloria melisma is a 16-note rise-
  and-fall that dramatically descends a full octave; previous version
  was 15 notes spanning only a 6th
- Hark the Herald Angels Sing: confirmed this hymn is truly strophic —
  "Joyful, all ye nations rise" is sung to the exact same tune as "Hark!
  the herald angels sing," not a different melody. Rebuilt from an
  invented chorus+verse alternation into one repeated 8-line stanza tune
  with a closing reprise of just the opening couplet, matching the score
- O Come All Ye Faithful: "O come, let us adore Him" is a descending
  sequence — the same phrase shape repeated a step lower each time — not
  one phrase repeated verbatim three times
- What Child Is This: the hymn is published in E minor with its own
  confirmed melodic shape, distinct in some details from the Greensleeves
  transcription elsewhere in this file; corrected to the hymn's own
  source rather than assuming the two are pitch-for-pitch identical

Also fetched and read an actual public-domain score for 12 Days of
Christmas and We Wish You a Merry Christmas: both confirmed the existing
content (cumulative day-by-day structure, and the earlier New Year's
ending fix, respectively) without needing further changes.

Molly Malone, Whiskey in the Jar, and Cielito Lindo: attempted the same
verification, but couldn't reach a fetchable note-level source for these
(several sites blocked automated fetches); their content is unchanged
from the prior pass and remains a best-effort construction rather than
source-verified.
