feat: add statusline function

Browse source 
Problem: no way to expose compiling/watching state to statusline
plugins like lualine or heirline without polling status() and
formatting it manually.

Solution: add `require('preview').statusline()` that returns
'compiling', 'watching', or '' for direct use in statusline components.
