Remove clean pre-build step

[dapplion]

Motivation

Current root yarn build command always cleans up existing lib artifacts. This prevents using incremental builds on the default command

Description

• Make default build command not clean
• Build may fail in some cases due to old build files lingering around. In that case run: yarn clean && yarn build
• CI runs will produce the same result as they start with no pre-existing lib files
