## Changes
- **What**: Implemented tooltip functionality for Vue node headers,
input/output slots, and widgets using [PrimeVue
v-tooltip](https://primevue.org/tooltip/) directive
- **Dependencies**: Leverages existing PrimeVue tooltip system, no new
dependencies
## Review Focus
Container scoping implementation via provide/inject pattern for tooltip
positioning, proper TypeScript interfaces eliminating `as any` casts,
and integration with existing settings store for tooltip delays and
enable/disable functionality.
