Helix 25.07

As always, a big thank you to all of the contributors! This release saw changes from 195 contributors.

Breaking changes:

• The parsing of the command line has been rewritten and now supports flags and expansions (#12527, #13018, 9574e55, 2d4c2a1, #13192, 67f1fe2, #13466, #13467, #13840)
  • Quoting and spaces are now handled differently. This can break existing keymaps which use typable commands, in particular :sh, :set-option or :toggle-option.
  • The :rsort command has been removed. Use the reverse flag instead: :sort --reverse
