The delegate used a ColumnLayout root with parent-dependent width
fallbacks (: 0, : 100) causing two-pass layouts. Combined with
onContentHeightChanged -> positionViewAtEnd(), this created a
feedback loop: height change -> scroll -> refill -> new delegates ->
height change -> ... burning 100% CPU on the main thread.
Fixes:
- Replace onContentHeightChanged with onCountChanged + Qt.callLater
- Replace ColumnLayout root with plain Column
- Bind all child widths to root.width (top-down, no fallbacks)
- Create context Menu lazily on first right-click
- Add reuseItems: true to the ListView
- Standardize bin path to ~/.local/bin
