fix: enable all tests

[klkvr]

it seems that we had incorrect cargo nextest args which caused tests under ./tests to never run

CI failure related to https://github.com/foundry-rs/foundry/issues/7797

Addressed this by rewriting path resolution logic for artifacts. Changes:

• Remove artifacts for dirty cache entries
• Just sort files by number of components when resolving paths instead of finding top-most
• Keep track of a single taken_paths_lowercase instead of keeping contracts in groups keyed by MappedContract.
• Deduplicated logic for artifact paths creation for contracts and standalone sources by extracing most of the logic into ArtifactOutput::get_artifact_path

A lot of WIndows tests were outdated, updated those. Will address clippy failure in #115

@mattsse ptal, added some changes using slash_paths here and there

Updated tests to use fd_lock for locking installer, should be less flaky now
