feat(compiler): notify on toggle watch start and stop (#13)

Browse source 
Problem: :Preview toggle gave no feedback, leaving the user to guess
whether watching was enabled or disabled.

Solution: emit vim.notify messages when toggling on ("watching with
\"<provider>\"") and off ("watching stopped"). Also normalize the
[preview.nvim] prefix in commands.lua to include the colon.
