fix: Lineno alignment, hl_mode, config options

- Config
  - Renamed auto_goto -> auto_jump (because goto implies change of
    cursor focus)
  - Renamed down/up_and_goto -> down/up_and_jump

Existing config that use the old keys *WILL STILL WORK*. But users are
recommended to update to avoid inconsistency. I promise the number of
config changes like this will decrease inverse-exponentially after the
plugin refactor :)

- Docs
  - Improved wording

- Lineno
  - Fixed alignment (no way I was taking max line num of the *Outline*
    buf this whole time!)
  - Fixed appearance of lineno column hl blending if hide_cursor is one
    (please see the comment added)
