Should be reasonably straightforward to do in flymake-harper.  Proceed
exactly like eglot.el does.  AFAIR it is a strict user of Flymake's
interfaces.

- make Flymake error category symbols for harper diagnostics
- when making diagnostics, add the correction meta-info (I presume it is
  available) in the flymake-make-diagnostic call
- use flymake-overlay-control on those category symbols.  Add a keymap,
- make a new flymake-harper command and put it on the map.  The command
  uses meta-info and does the correction
- the map is activated when you click the flymake overlay

If you want to autocorrect a number of diagnostics, make a command that
uses flymake-diagnostics to get all diags in a region and iterate.

Alternatively, possibly just using harper-ls and/or multiplexing with
any other language server you are using is also a decent idea that
doesn't require a separate Flymake backend.
