test: speed up (#1386)

Reduce redundant fixture setup, Git subprocesses, and large data copies while preserving test coverage.

Local macOS measurements against main:

| Measurement | Before | After |
| --- | ---: | ---: |
| Git package time, median of 3 alternating runs | 4.09 s | 3.48 s (-15%) |
| Allocations across 18 action-bundle cases | 489 MiB | 251 MiB (-49%) |
| Traced Git starts per checkout table run | 234 | 175 |
