Avoid repeated CLI startup when preparing integration fixtures (#917)

Prepare installed hooks through `Overcommit::Installer` when
installation is only integration-test setup. This avoids repeatedly
starting Ruby and loading the CLI before exercising a commit, push,
signing, merge, or concurrency behavior. Dedicated CLI/installation and
Gemfile-loading tests retain their real executable calls; every example
and assertion remains.

The helper clears repository-path caches before and after installation
so setup cannot inherit a previous example's repository or leak its own
paths. Fixture logging is captured in memory.

[Paired Windows CI
experiment](https://github.com/sds/overcommit/actions/runs/42086970366)
on Ruby 3.4 compared unchanged code and this setup on the same VM,
alternating order across all five production shards:

| Shard | Control | Installer API |
| --- | --- | --- |
| 1 | 30.70s | 27.49s |
| 2 | 41.13s | 38.91s |
| 3 | 49.90s | 43.21s |
| 4 | 47.62s | 45.84s |
| 5 | 35.08s | 29.11s |

All five candidates passed and were faster in both execution orders:
median paired reduction 10.5%, aggregate test-command reduction 9.7%.

Local validation: all 90 integration examples pass, RuboCop passes, and
`git diff --check` passes. Final full Ruby/OS PR-head verification is
pending; merge only after it passes and confirms the improvement.
