[mpp-idea] Refactor IdeaSketchRenderer to reuse LangSketch business logic from core module

[phodal]

Overview

Refactor IdeaSketchRenderer in mpp-idea module to reuse business logic from core module's LangSketch components while keeping the Compose UI implementation.

Background

• mpp-idea: Uses Compose for Desktop (Jewel) - currently only static rendering
• core: Uses Swing (JComponent) - full functionality (Apply/Reject/Repair/View Diff, etc.)

Approach: Solution B

Reimplement UI in Compose while reusing core's business logic to avoid SwingPanel z-index issues.

LangSketch Components to Migrate

Core Module

Component	Language	Priority
CodeHighlightSketch	All code	P0
DiffLangSketch	diff, patch	P0
SingleFileDiffSketch	-	P0
PlanLangSketch	plan	P1
HtmlHighlightSketch	html	P1
WebpageLangSketch	html (full page)	P2
MarkdownPreviewHighlightSketch	markdown	P2
OpenAPISketch	yaml, yml	P3

Extension Modules

Component	Module	Language	Priority
TerminalLangSketch	ext-terminal	bash, shell	P1
MermaidSketch	ext-mermaid	mermaid	P2
PlantUmlSketch	ext-plantuml	plantuml, puml	P3
GraphvizSketch	ext-diagram	dot, graphviz	P3
GoLangPlaygroundSketch	goland	go	P3

Reusable Business Logic

Logic	Location	Method
Diff parsing	mpp-core	DiffParser.parse()
Patch apply	core	PatchProcessor.applyPatch()
Patch repair	core	DiffRepair.applyDiffRepairSuggestion()
Diff dialog	core	showSingleDiff()
Plan parsing	core	MarkdownPlanParser.parse()
Shell safety	core	ShellSafetyCheck.checkDangerousCommand()

Implementation Phases

Phase 1: IdeaDiffActions (P0) ✅ COMPLETED

• Create IdeaDiffActions.kt with accept/reject/viewDiff/repair methods
• Update IdeaDiffRenderer.kt with action buttons
• Reuse PatchProcessor, DiffRepair, showSingleDiff()

Files created/modified:

• mpp-idea/src/main/kotlin/cc/unitmesh/devins/idea/renderer/sketch/actions/IdeaDiffActions.kt
• mpp-idea/src/main/kotlin/cc/unitmesh/devins/idea/renderer/sketch/IdeaDiffRenderer.kt
• mpp-idea/src/main/kotlin/cc/unitmesh/devins/idea/renderer/sketch/IdeaSketchRenderer.kt

Phase 2: IdeaCodeActions (P1)

• Create IdeaCodeActions.kt with copy/insert/newFile methods
• Update IdeaCodeBlockRenderer.kt with toolbar

Phase 3: IdeaPlanRenderer (P1)

• Create IdeaPlanRenderer.kt
• Reuse MarkdownPlanParser.parse()
• Support Pin/Compress features

Phase 4: IdeaTerminalRenderer (P2)

• Create IdeaTerminalRenderer.kt
• Reuse ShellSafetyCheck
• Depends on ext-terminal module

Phase 5: Diagram Enhancements (P3)

• Enhance existing IdeaMermaidRenderer
• Add PlantUML/Graphviz support (optional)

Notes

1. Use DialogWrapper for complex Swing components to avoid z-index issues
2. Use Jewel's IconButton for action buttons
3. Maintain feature parity with core module Sketches
