feat(mpp-idea): Enhance IdeaFileSearchPopup with full context menu features

[phodal]

Background

The current IdeaFileSearchPopup implementation needs to be enhanced to match the full context menu design (see screenshot) and integrate features from RelatedFileWorkspaceManager.

Current State

IdeaFileSearchPopup.kt currently has:

• Files submenu (search files)
• Folders submenu (search folders)
• Recently Opened Files submenu
• Clear Context option
• Bottom search field

Target Design


Default Context
Files                    >
Folders                  >
Recently Opened Files    >
Rules                    >
Clear Context
─────────────────────────
[ Focus context         ]

Required Changes

1. New Menu Items

• Default Context: Add option to set/clear default context
• Rules: Add submenu for context rules (TBD: what rules?)

2. UI Improvements

• Path display format: Show truncated paths like ...cc/unitmesh/devins/idea/editor
• File item layout: FileName.kt ...path/to/file (name bold, path gray)
• History icon: Add IdeaComposeIcons.History for Recently Opened Files

3. Integration with RelatedFileWorkspaceManager Pattern

• Auto-add current file: Listen to FileEditorManagerListener to auto-add current file to context
• Related classes: Listen to LookupManagerListener to suggest related classes
• Workspace panel: Create equivalent of WorkspaceFilePanel for managing selected files
• File list visualization: Show selected files as chips/tags in toolbar

4. Technical Implementation

// New structure needed:
class IdeaContextManager(project: Project) {
    // State management for selected files
    val selectedFiles: StateFlow<List<VirtualFile>>
    
    // Auto-add current editor file
    fun setupEditorListener()
    
    // Related classes from lookup
    fun setupRelatedClassesListener()
    
    // Clear all context
    fun clearContext()
    
    // Set default context
    fun setDefaultContext(files: List<VirtualFile>)
}

Questions to Clarify

1. Default Context: What should this do? Save a preset of files?
2. Rules: What kind of rules? File patterns? Include/exclude rules?
3. Integration scope: Should this replace or complement the existing file selection in IdeaTopToolbar?
