Performance optimizations for large vaults:
- Barnes-Hut quadtree repulsion (O(n log n) for >200 nodes)
- Naive O(n²) preserved for small graphs (<200 nodes)
- Graph cache: reuse data when same (vault, path, depth, scope, tag)
- Cache key displayed in info bar: '(cache)' label
Backend (main.py):
- GraphNode: added tags, incoming_count, outgoing_count
- GraphEdge: added 'backlink' relation
- GraphResponse: added 'scope' field
- api_graph: scope=full|directory, tag= filter, backlinks
- Full-vault tree walk with configurable depth 0-3
- Tag index from in-memory file index for fast filtering
- Incoming/outgoing link count per node
Frontend (graph.js + index.html):
- Theme-adaptive colors via CSS custom properties
- Depth slider (0-3) with live reload
- Full-vault toggle button (🌐 Tout / 📁 Dossier)
- Search input with tag filtering + visual highlighting
- Tooltip on hover (name, path, tags, link counts)
- Backlink edges rendered in red dashed
- Node size proportional to link count
- Larger modal (1000px, 85vh)
Remove the old HTML-based PDF download endpoint in favor of the new
WeasyPrint-based one, and replace the generic "Télécharger" button
in popout.html with a dedicated .md download and a new PDF button.
Also remove the unused generic download button from the main file view.

export buttons
- Update bookmark button to reflect current state with visual feedback
- Introduce CSS custom properties for theming and responsive layout
improvements
- Add automatic Content-Type header injection for JSON string bodies
- Explicitly set Content-Type on bookmark toggle and share creation
calls
- Add escapeHtml helper function for safe string handling
- Add bookmark button to file header and context menu
- Implement toggle bookmark API call with toast notification
- Redesign share dialog to show existing shares with revocation
- Add expiration options when creating a new share

Implement several security and feature improvements across the backend
and frontend:
- New IP-based rate limiter for authentication endpoints
- New audit logging system for sensitive operations
- New secret redactor to mask sensitive patterns in rendered content
- Configurable token TTL and IGNORED_DIRS via environment variables
- Add backlink index and API endpoint
- Add preview tab support with single/double-click behavior in tree
- Add file backup before write/delete operations
Implement `incrementalLoadDirectory` to update tree items without full
DOM
rebuild. Modify `refreshSidebarTreePreservingState` to use incremental
updates for expanded vaults and directories, preserving existing DOM
state.
- Add cdnjs.cloudflare.com, fonts.googleapis.com, and fonts.gstatic.com to connect-src CSP directive
- Add waitForHljs helper function with 50 attempt limit and 100ms polling interval
- Check if hljs is defined before highlighting code blocks in popout view
- Fall back to async waiting if hljs not immediately available to prevent undefined reference errors
- Extract expandDirectoryInSidebar function to handle directory expansion logic with loading and chevron icon updates
- Replace inline directory expansion code in focusPathInSidebar with calls to new helper function
- Add busy state tracking to breadcrumb click handlers to prevent rapid successive clicks
- Disable pointer events during breadcrumb navigation execution
- Make breadcrumb onClick handlers async to support
- Add "center" alignment option to scrollToElement function alongside existing top/default alignment
- Calculate centered scroll position by centering element vertically in viewport
- Update all breadcrumb navigation calls to use center alignment instead of top/false alignment
- Refactor targetTop calculation with ternary operator for cleaner conditional logic
- Extract getParentDirectoryPath helper to get parent directory from file path
- Extract syncActiveFileTreeItem helper to manage active tree item highlighting
- Update dashboard file navigation to focus parent directory with expansion instead of file itself
- Manually sync active state after navigation to ensure file is highlighted in tree
- Refactor openFile to use new syncActiveFileTreeItem helper
- Add expandTarget option to focusPathInSidebar function to control directory expansion behavior
- Check if target directory is collapsed and click to expand before highlighting
- Pass expandTarget: true when navigating to directories from dashboard to ensure visibility
- Add async delay after expansion to allow DOM update before path highlighting
- Add ext: operator support to query parser in backend and frontend
- Update search documentation in README and help modal with ext: examples
- Parse ext: operator to extract file extension filter (strips leading dot, converts to lowercase)
- Filter search candidates by file extension in advanced_search function
- Add ext chip display in search UI alongside existing tag/vault/title/path chips
- Update API documentation and function
