Add children support for nested menu items with hover-triggered
submenus, auto-flip positioning near viewport edges, and smart
close timing to prevent flicker.
The reka-ui ContextMenu component caused significant performance
degradation when multiple editor tabs were cached via KeepAlive,
due to its heavy state machine, provide/inject chain, and document-level
event listeners accumulating across cached instances.
Replaced with a minimal CustomContextMenu that renders via Teleport
without any DOM wrapping or reka-ui dependency, eliminating the lag
while preserving the same visual appearance and functionality.
Add useSqlHighlighter composable and integrate Shiki highlighting into
DangerConfirmDialog, QueryHistory, DataGrid (replacing regex-based
highlighting), SqlFileExecutionDialog, SchemaDiffDialog, TreeItem,
ObjectBrowser, and FieldLineageDialog. Also fix danger dialog overflow
by adding overflow-hidden to DialogContent and wrap/scroll support.
