[DomEvent] Implement 3-Phase Boundary-Aware Delegation Verification

Refactor Neo.manager.DomEvent.verifyDelegationPath to support robust, boundary-aware delegation verification for complex component hierarchies.

Problem: The previous implementation only verified delegation targets against the physical DOM path. This caused failures for:

1. Detached VDOM Components: Components physically rendered elsewhere (e.g., Portals, DragProxies) but present in the listener's VDOM.
2. Logical Child Components: Components linked via parentComponent (e.g., Floating Menus) which are neither physically nested nor in the listener's VDOM.

Solution: Implement a 3-Phase Verification Strategy in verifyDelegationPath to balance performance and correctness:

1. Phase 1: Physical Boundary Check (The Fast Path)

   • Iterates the raw event.path provided by the browser.
   • Checks if the delegationTarget is physically contained within the listener.vnodeId.
   • Performance: Covers ~99% of standard inline events with O(N) efficiency.

2. Phase 2: Logical VNode Verification (The VDOM Fallback)

   • Triggered only if Phase 1 fails.
   • Uses Neo.util.VNode.getById(listenerComponent.vnode, targetId) to verify if the target exists within the listener's logical VNode tree.
   • Use Case: Portals, DragProxies, and other VDOM-connected but physically detached components.
   • Note: correctly resolves component references to "tunnel" into child component VNodes.

3. Phase 3: Logical Component Path Verification (The Last Resort)

   • Triggered only if Phase 2 fails.
   • Checks the logical componentPath (constructed via ComponentManager from parent/parentComponent chains).
   • Verifies that the target's component ID is logically "below" or same as the listener's component ID in the hierarchy.
   • Use Case: Floating Menus and other purely logical children (linked via parentComponent) that are roots of their own VDOM trees.

Changes:

• Modified src/manager/DomEvent.mjs to implement the 3-phase logic.
• Added test/playwright/unit/manager/domEvent/Delegation.spec.mjs with comprehensive test cases for all scenarios:
  • Physical nesting (Standard)
  • VDOM connection (Portal/Proxy)
  • Logical connection (Menu/ParentComponent)
  • Negative case (Random element)
