fix: normalize Vyper EVM version during input creation (#345)
## Summary `VyperInput::new()` was calling `sanitize_output_selection()` instead of `sanitize()`, which meant `normalize_evm_version()` was never invoked during input creation. This caused compilation failures when using EVM versions not supported by the Vyper compiler version. For example, using `osaka` (the new default in Foundry) with Vyper 0.4.3 would fail with: ``` Error: Compiler run failed: Location: <stdin> Unknown EVM version - 'osaka' ``` ## Fix Call `sanitize()` instead of `sanitize_output_selection()` in `VyperInput::new()`. The `sanitize()` method already calls both `sanitize_output_selection()` and `normalize_evm_version()`, so this ensures the EVM version is properly downgraded to the maximum supported by the Vyper version (e.g., `prague` for Vyper 0.4.3).
