koii-test-validator broken on macOS

Running the `koii-test-validator` command yields the following output:
```
❯ koii-test-validator
Ledger location: test-ledger
Log: test-ledger/validator.log
Error: failed to start validator: Failed to create ledger at test-ledger: blockstore error
```

System info:
```
❯ sw_vers
ProductName: macOS
ProductVersion: 15.1
BuildVersion: 24B83
```

```
❯ koii --version
koii-cli 1.16.2 (src:devbuild; feat:2325450753)

❯ koii-test-validator --version
solana-test-validator 1.16.2 (src:devbuild; feat:2325450753)
```

Seems to be patched in solana-test-validator v2: https://github.com/solana-labs/solana/issues/34625

Start by reproducing `koii-test-validator` on macOS 15.1 with the reported 1.16.2 versions, then read the linked Solana issue about the v2 patch. Done means the validator creates the test ledger and starts successfully on macOS.
