Update package creation: `lake init .` uses current dir name, disallows invalid pkg names, no uppercase conversion for `lean_lib`, supports non-ident libs, filters irrelevant env extensions, re-unpacks cloud releases, simpler math template, parse build targets in `lake exe`, shadowing for later packages, excludes exe roots from importable modules.
