tegwick 4576d066b3 feat: add inline file editing with modification tracking and save functionality
Add comprehensive inline editing capabilities for all project files with visual modification tracking and batch save functionality.

Features:
- Edit buttons next to each file load button (Project, SVG, CSS, CSV)
- Modal editor with syntax validation for JSON files
- Real-time preview updates after applying changes
- Visual "MODIFIED" badges on edited files
- "Save Changes" button to download all modified files
- Keyboard shortcuts (Escape to close editor)

Implementation:
- file-editor.js: New module handling all editor functionality
  - Editor modal with textarea for content editing
  - Modification tracking using Set data structure
  - File-specific validation (JSON syntax checking)
  - Batch download of all modified files
  - Visual badge updates for modified state

- index.html: UI updates
  - Edit buttons added to all file items
  - Modal HTML structure for editor
  - Save Changes button in controls area
  - CSS styling for editor modal and modified badges

- engine.js: Integration and data storage
  - Store CSV and CSS content when loaded (for editing)
  - Enable edit buttons when files are successfully loaded
  - Works with all loading methods (folder picker, individual files, auto-load)
  - CSS now loaded via fetch to store content (changed from link href)

- Makefile: Include file-editor.js in distribution build

User workflow:
1. Load project files (folder picker or individual files)
2. Click "✏️ Edit" button next to any file
3. Make changes in modal editor
4. Click "Apply Changes" to update and see immediate preview
5. Modified files show orange "MODIFIED" badge
6. Click "💾 Save Changes" to download all modified files at once

Technical details:
- Edit buttons start disabled, enabled when file loads
- JSON validation prevents saving invalid configurations
- Changes apply immediately to in-memory data
- Timeline regenerates automatically after edits
- Modified state persists until files are saved
- Optional clearing of modified state after download
