Subject: operate: mover, opener, runner, clipboard modules + tests (ut0)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

M8 (partial): plain-C operate modules + unit tests.

- src/mover.{c,h}: move files to configured dests (g_file_move + stem
  collision suffix -1/-2), one-level undo (move back), acts on marks-or-current.
- src/opener.{c,h}: %f expand + detached GSubprocess launch (non-blocking).
- src/runner.{c,h}: /bin/sh -c with single-quoted %f/%d (injection guard),
  async wait_check, rescan on completion.
- src/clipboard.{c,h}: image/png via GdkContentProvider + uri-list.
- meson: new sources added to libggae.
- tests: unit test_mover (move/undo/collision), test_opener (true/false/weird
  filenames), test_runner (true/false/injection guard). 19/19 green, ASan clean.
- Fixed: g_str_replace (not in GLib 2.88) → manual _str_replace; GdkContentProvider
  API (new_typed/new_for_value); mover collision stem-suffix; runner /bin/sh -c
  argv (single arg, not shell-parsed); test GFile leaks.
