make it easier to implement cycle management

- prevent bad permissions if possible
- fix bad permissions with single chmod command
- join multiple jq calls
- make electron wrapping more readable

- works out-of-the-box, no node|tsc settings necessary
- optimal use of storage, composable
- handles cyclic dependencies by co-locating cycles in the same store path

Changes:
- build node_modules as a separate derivation, use everywhere
- if main package has a build script, run it with dev modules and
  afterwards run install script if present, then switch to prod modules
- only run build scripts when necessary, speedup
- optionally add all transitive binaries to the node_modules/.bin
- store binaries in bin/
  NixOS standard location, and .bin should only be used for dependencies,
  not the main package
- in a package, .bin is now a symlink to bin
- in bin name, strip .js ending for string case
- remove now-unnecessary code

This builder requires all peer dependencies for packages to be mentioned and all transitive circular dependencies to be grouped

- discovers peer dependencies correctly
- adds metadata like os, dev and hasInstallScripts to sources
