[refactor] Migrate minimap to domain-driven renderer architecture (#5069)

* move ref initialization to the component

* remove redundant init

* [refactor] Move minimap to domain-driven renderer structure

- Create new src/renderer/extensions/minimap/ structure following domain-driven design
- Add composables: useMinimapGraph, useMinimapViewport, useMinimapRenderer, useMinimapInteraction, useMinimapSettings
- Add minimapCanvasRenderer with efficient batched rendering
- Add comprehensive type definitions in types.ts
- Remove old src/composables/useMinimap.ts composable
- Implement proper separation of concerns with dedicated composables for each domain

The new structure provides cleaner APIs, better performance through batched rendering,
and improved maintainability through domain separation.

* [test] Fix minimap tests for new renderer structure

- Update all test imports to use new renderer paths
- Fix mock implementations to match new composable APIs
- Add proper RAF mocking for throttled functions
- Fix type assertions to handle strict TypeScript checks
- Update test expectations for new implementation behavior
- Fix viewport transform calculations in tests
- Handle async/throttled behavior correctly in tests

All 28 minimap tests now passing with new architecture.

* [fix] Remove unused init import in MiniMap component

* [refactor] Move useWorkflowThumbnail to renderer/thumbnail structure

- Moved useWorkflowThumbnail from src/composables to src/renderer/thumbnail/composables
- Updated all imports in components, stores and services
- Moved test file to match new structure
- This ensures all rendering-related composables live in the renderer directory

* [test] Fix minimap canvas renderer test for connections

- Fixed mock setup for graph links to match LiteGraph's hybrid Map/Object structure
- LiteGraph expects links to be accessible both as a Map and as an object
- Test now properly verifies connection rendering functionality

+   - Internal refactoring

-2. **Analyze for GTM-worthy features:**
-   ```
-   <task>
-   Review these PRs to identify if ANY would interest a marketing/growth team.
-   
-   Consider if a PR:
-   - Changes something users directly interact with or experience
-   - Makes something noticeably better, faster, or easier
-   - Introduces capabilities users have been asking for
-   - Has visual assets (screenshots, GIFs, videos) that could be shared
-   - Tells a compelling story about improvement or innovation
-   - Would make users excited if they heard about it
-   
-   Many releases contain only technical improvements, bug fixes, or internal changes - 
-   that's perfectly normal. Only flag PRs that would genuinely interest end users.
-   
-   If you find marketing-worthy PRs, note:
-   - PR number, title, and author
-   - Any media links from the description
-   - One sentence on why it's worth showcasing
-   
-   If nothing is marketing-worthy, just say "No marketing-worthy features in this release."
-   </task>
-   
-   PR data: [contents of prs-${NEW_VERSION}.json]
-   ```
-
-3. **Generate GTM notification (only if needed):**
-   ```
-   If there are marketing-worthy features, create a message for #gtm with:
-   
-   🚀 Frontend Release v${NEW_VERSION}
-   
-   Timeline: Available now in nightly, ~2-3 weeks for core
-   
-   Features worth showcasing:
-   [List the selected PRs with media links and authors]
-   
-   Testing: --front-end-version ${NEW_VERSION}
-   
-   If there are NO marketing-worthy features, generate:
-   "No marketing-worthy features in v${NEW_VERSION} - mostly internal improvements and bug fixes."
-   ```
-
-4. **Save the output:**
-   ```bash
-   # Claude generates the GTM summary and saves it
