Unit and integration runs

Testing-plan rows T1–T7, after the change.

T1, T2, T3, T6 — the excerpt's own units

$ uv run pytest cli/tests/test_excerpt.py -q
............................                                             [100%]
28 passed in 0.06s

T6 — the abuse cases alone

$ uv run pytest cli/tests/test_excerpt.py -k abuse -q
........                                                                 [100%]
8 passed, 20 deselected in 0.03s

T4, T5 — the two ingresses, and the gates

$ uv run pytest cli/tests/test_excerpt_integration.py -q
....                                                                     [100%]
4 passed in 0.05s

T7 — the whole suite

$ uv run pytest cli -q
.....................................................................    [100%]
2156 passed, 1 skipped in 110.54s (0:01:50)

The integration tests, red first

T4/T5 were written after the wiring, so their red was captured by restoring the pre-change excerpt.py (commit 08b7bd6) under the already-wired dispatcher — the wiring alone changes nothing while the distiller is the old one:

$ git show 08b7bd6:cli/the_loop/webhook/excerpt.py > cli/the_loop/webhook/excerpt.py
