Enable a different lazy evaluation strategy for streams

[onurkerimov]

• Enable plugins as use.plugins array
• Upgrade devtools package to work with the new plugin runtime
• Add "Using immer" recipe
• Shave off a few bytes from the main package and move it to @xoid/lite
• Stream runtime now has an internal "pending" state.
  • There's now a way for making mapped (non-stream) atoms evaluate by destructuring their .value.
• Focus atoms are now using internal.atom.set instead of internal.set to provide consistency in enhanced atoms.
