Fine-track `org-agenda-files' to speed-up `org-ql-views'

When an agenda buffer is built, Emacs visits each file listed in
`org-agenda-files'.  In case your tasks or events are recorded in
an ever-extending journal and/or roam directories, `org-agenda' can
become sluggish.
This package aims to dynamically update the `org-agenda-files'
variable by appending/deleting a candidate org file when it is
saved.  This limits the number of files to visit when building the
agenda.  The agenda buffer thus builds faster.  Candidate selection
logic is extracted from `org-agenda-custom-commands' and
`org-ql-views'.
