Scenario: sync-model

The state the README and the sync model draw: both sides moved on since the clone, and nothing was pulled or pushed yet. The commits are named as in the drawing:

Monorepo commits a to d, upstream commits k to n, and the rebuilt commits b prime and d prime on top of k: U(H) = U(B) = k

Monorepo (vendor/a/): cloned at k in a, then b and d change the folder, c changes another one.
Upstream: k, then l, m and n, fetched.

after-pull continues with the pull.

Output

setup.bash builds this state:

$ build_scenario scenario_sync_model

The drawing shows what Git and git-splice say about it. a is the clone, add vendor/a, which isn't a subject the drawing can show, so it's named by its place in the history (check_drawing):

$ check_drawing "$TESTDIR/before-pull.drawio.svg" a=HEAD~3
ok   before-pull.drawio.svg: 10 commits, 13 arrows, 5 boxes, 1 frames

R and T have each moved on from k:

$ git splice log --graph vendor/a
===  vendor/a (main)
< d4da194 (R) d  (Test <test@example.com>)
< 9ec734f b  (Test <test@example.com>)
| > df79a48 (T) n  (Test <test@example.com>)
| > d34c417 m  (Test <test@example.com>)
| > 5ba0fc7 l  (Test <test@example.com>)
|/  
o ae8b31f k  (Test <test@example.com>)
