Python 3.15 lazy imports.

Before:

Benchmark 1: .venv/bin/python -m repo_review --help
  Time (mean ± σ):     113.3 ms ±  59.8 ms    [User: 83.5 ms, System: 19.2 ms]
  Range (min … max):    85.9 ms … 273.9 ms    10 runs

After:

Benchmark 1: .venv/bin/python -m repo_review --help
  Time (mean ± σ):      66.7 ms ±   1.8 ms    [User: 53.6 ms, System: 10.9 ms]
  Range (min … max):    64.1 ms …  70.9 ms    40 runs

If CPython Rich would implement lazy imports:

Benchmark 1: .venv/bin/python -X lazy_imports=all -m repo_review --help
  Time (mean ± σ):      45.7 ms ±   0.6 ms    [User: 36.6 ms, System: 6.9 ms]
  Range (min … max):    44.6 ms …  47.0 ms    60 runs

I got it down even further in #317.
