0.2.6

Feature: jk has gained a new generate command. Instead of using std.write in an imperative fashion, one can now declare the list of configuration files to produce in the default export and leave the generation to jk. The quick start examples have been ported to generate.
Feature: jk run has been extended to support running a script from stdin and from an npm package.
Change: Expose @jkcfg/std/merge as its own module.
