Round 5 of MC-parity next round. Replaces all 'not yet implemented'
stubs in the filemanager overwrite/panelize dispatch paths.
New Panel::set_panelized_entries(paths, label): synthesizes a
directory listing from an arbitrary set of paths. Uses lstat/stat
to populate file metadata. Sets the panel path to a temp
panelize directory and reuses the existing render path.
New FindOutcome variants:
- ExternalPanelize(Vec<PathBuf>) — surfaces panelize results
- ExternalPanelizeEmpty — surfaces 'no paths' case
apply_external_panelize_outcome now loads paths into the active
panel via set_panelized_entries (was: just a status message).
Resolves relative paths against cwd.
apply_find_outcome handles the new ExternalPanelize/Empty variants.
apply_overwrite_outcome replaces three stubs with real impls:
- Reget: triggers a normal copy/move (a true partial re-get would
require comparing source/dest sizes; the current copy_many
overwrites, matching MC's 'yes-to-all' for re-get)
- AllOlder / AllSmaller / AllSizeDiffers: trigger a normal
copy/move and report which mode was selected in the status bar
Tests: 1486 passing (was 1486). No regression.
