refactor(manifest): centralize build directory creation logic

Automatically create build directories for all commands that need them,
including build, install, autoprovides, and test. This removes duplicate
code and ensures consistent behavior across commands. The test command
now also supports automatic temporary directory creation when no build
path is provided.
