Problem: Some runtime files no longer spark joy.

Solution: Kondo the place up.

Still sparks _some_ joy (moved to new `runtime/scripts` folder):
* `macros/less.*`
* `mswin.vim`
* `tools/emoji_list.lua`

No longer sparks joy (removed):
* `macmap.vim` (gvimrc file; not useful in Nvim)
* `tools/check_colors.vim` (no longer useful with new default colorscheme and treesitter)
* `macros/editexisting.vim` (throws error on current Nvim)
* `macros/justify.vim` (obsolete shim for `packadd! justify`)
* `macros/matchit.vim` (same)
* `macros/shellmenu.vim` (same)
* `macros/swapmous.vim` (same)

- all: PMenuMatch and PMenuMatchSel for 8c/16c
- habamax:
    - revert VertSplit to solid background color
    - remove gitCommitSummary link to Title
    - make TabLineFill same as StatuslineNC

Magenta background Todo is too bright and might interfere with DiffText.
Make it less strong, without background, bold.

Problem: both `StatusLineTerm`/`StatusLineTermNC` are now explicitly
  used, but `:color vim` does not set them to the values used in Vim.
  This might be fine if `:color vim` is treated as "the state of default
  color scheme prior the big update", but it seems to be better treated
  as "Vim's default color scheme" (how it is documented in its header).

Solution: add `StatusLineTerm`/`StatusLineTermNC` definitions to
  'runtime/colors/vim.lua'.
  Use explicit foreground colors ('Whte'/'Black') instead of `guifg=bg`
  used in source, as the latter caused some problems in the past (if
  `Normal` is not defined, `nvim_set_hl()` can't recognize `'bg'` as the
  foreground value).
  Also realign the rest of the background conditional highlight groups.
