Fetch concurrently for non-first-match index strategies (#10432) 
## Summary

On a basic test, this speeds up cold resolution by about 25%:

```
❯ hyperfine "uv lock --extra-index-url https://download.pytorch.org/whl/cpu --index-strategy unsafe-best-match --upgrade --no-cache" "../target/release/uv lock --extra-index-url https://download.pytorch.org/whl/cpu --index-strategy unsafe-best-match --upgrade --no-cache" --warmup 10 --runs 30
Benchmark 1: uv lock --extra-index-url https://download.pytorch.org/whl/cpu --index-strategy unsafe-best-match --upgrade --no-cache
  Time (mean ± σ):     585.8 ms ±  28.2 ms    [User: 149.7 ms, System: 97.4 ms]
  Range (min … max):   541.5 ms … 654.8 ms    30 runs

Benchmark 2: ../target/release/uv lock --extra-index-url https://download.pytorch.org/whl/cpu --index-strategy unsafe-best-match --upgrade --no-cache
  Time (mean ± σ):     468.3 ms ±  52.0 ms    [User: 131.7 ms, System: 76.9 ms]
  Range (min … max):   380.2 ms … 607.0 ms    30 runs

Summary
  ../target/release/uv lock --extra-index-url https://download.pytorch.org/whl/cpu --index-strategy unsafe-best-match --upgrade --no-cache ran
    1.25 ± 0.15 times faster than uv lock --extra-index-url https://download.pytorch.org/whl/cpu --index-strategy unsafe-best-match --upgrade --no-cache
```

Given:
```toml
[project]
name = "foo"
version = "0.1.0"
description = "Add your description here"
readme = "README.md"

]
```

And:

```shell
hyperfine "uv lock --extra-index-url https://download.pytorch.org/whl/cpu --index-strategy unsafe-best-match --upgrade --no-cache" "../target/release/uv lock --extra-index-url https://download.pytorch.org/whl/cpu --index-strategy unsafe-best-match --upgrade --no-cache" --warmup 10 --runs 30
