fix(editor): fix global shortcut interception, scroll view centering,…

[ThisIs-Developer]

Summary of Completed Fixes:

1. Global Shortcut Interception (Ctrl + F & Ctrl + H): Migrated the event listeners from the local markdownEditor keydown event to the global document node. Keyboard shortcuts are now globally intercepted across all focus regions, preventing the browser default Find box.
2. Floating Panel Position Reset: Added coordinate clearing to the panel close routine. Dragging positions are cleared so that every time the floating panel is reopened, it returns to its default top-right corner.
3. Smooth Dock Transitions: Re-engineered the panel's DOM detaching and re-attaching sequences to occur instantly without panel resets, display hides, or search parameter losses.
4. Display Mode State Persistence: Leveraged localStorage keys to cache and restore the user's last used mode preference (floating vs docked), separate from the dragging position resets.
5. Split View Layout Bounds: Modified the flex calculations in applyPaneWidths() and introduced a dynamic --dock-width property:
   • editorPaneElement.style.flex = 0 0 calc((100% - var(--dock-width, 0px)) * ratio - 4px)
   • Both editor and preview panes now scale proportionally to fit exactly inside the screen container alongside the docked panel, preventing overlap.
6. Search Highlights & Navigation Centering:
   • Text Blur Fix: Set color: transparent !important; on .find-highlight and .find-highlight.active classes. This keeps matching characters in the background highlight layer completely transparent, eliminating text doubling and fuzzy overlay rendering.
   • Auto-Scroll Fix: Integrated explicit vertical centering calculations into selectActiveMatch(), automatically scrolling the editor viewport to center focused match results during previous/next cycling.
