v3.6.0

=====================================================================

--- New Features -------------------------

- Introducing an optional plugin for `kubectl` facilitation! Check out
  'plugins/kubectl/README.md' for more details.

--- Changes ------------------------------

- The function which lists all available scwrypts now ignores
  directories with a top-level base called "plugins." If this is a name
  conflict, you will need to define your own
  `SCWRYPTS__LIST_AVAILABLE_SCWRYPTS__<group>` function!

  (ref the changes in 'zsh/lib/scwrypts/run.module.zsh')
