* feat: Add support showing size of absent git-annex'ed files

git-annex encodes the apparent size of files their symlinks.

gdu now is capable of extracting those sizes from the broken symlinks to calculate the total size of git-annex repositories.

Note: real usage remains zero. gdu needs to be invoked via:
    gdu --follow-symlinks --show-apparent-size --show-annexed-size

Closes #414

* WIP: Fix item count for --show-item-count (Issue #412) - Row display adjusted

This is a partial fix for issue #412 where `gdu --show-item-count`
incorrectly includes the directory itself in its item count.

Changes made so far:
- I investigated the analyzer logic (`pkg/analyze/*`) and determined that
  `Dir.ItemCount` is intentionally inclusive of the directory itself due
  to internal uses (e.g., ignored directories).
- I shifted the fix to the TUI layer to adjust the count only for display
  purposes when `--show-item-count` is active.
- I modified `tui/format.go` in the `formatFileRow` function:
  - If `ui.showItemCount` is true and the item is a directory, the
    displayed item count for that row is now `item.GetItemCount() - 1`.
  - Files continue to display their item count as is (0).

Pending work:
- I will modify `tui/show.go` to adjust the total item count displayed in the
  footer similarly.
- I will re-add and adjust `TestItemCount` in `pkg/analyze/dir_test.go` to
  assert the corrected user-facing item counts.
- I will run all tests to ensure correctness.

* fix: fmt
