v1.5.2: context-menu clipping fix, compact menu rows

Fixes

• Context menu clipping: the tree context menu no longer clips its lower items when opened low on the screen. Builderius positions the menu from the click point before our extra rows (Rename, Wrap in, Move up/down, Unwrap and so on) are added, and never re-measures, so a fully-loaded menu could run past the bottom of the viewport and hide its last actions. The menu is now re-clamped into view once the rows are in: shifted up to fit, or capped and scrolled when it is genuinely taller than the viewport. The Wrap in and Save to flyouts are unaffected.

Changes

• Compact menu rows: context-menu rows are tighter. The native menu's generous row padding made a loaded menu tall and sparse; rows now use slimmer padding (still above the 24px minimum pointer-target size for WCAG 2.2 AA) with lighter cluster separators, cutting a full menu's height by roughly a quarter. Native and injected rows, and the flyouts, all share the tighter spacing.
