feat: open inline images in lightbox

 - `SingleEditorView` disables BlockNote's default formatting toolbar, `/` menu, and side menu, then mounts Tolaria-owned controllers so the visible formatting surface matches Tolaria's markdown round-trip guarantees.
 - The formatting toolbar only exposes inline controls that persist through `blocksToMarkdownLossy()` in Tolaria's save pipeline: bold, italic, strike, nesting, and link creation. Controls that BlockNote can render temporarily but Tolaria cannot faithfully persist, such as underline, color, alignment, and the block-type dropdown, are hidden instead of appearing to work and later disappearing.
 - Tolaria's formatting-toolbar controller also keeps file/image actions mounted across the tiny hover gap between an image block and the floating toolbar, and while the toolbar itself is hovered, so image controls remain usable instead of collapsing mid-interaction.
+- `useImageLightbox` listens for `dblclick` on the rich-editor container and opens `ImageLightbox` only when the event target resolves to a viewable BlockNote image. The target resolver handles media wrappers, ignores image captions/resize controls, missing sources, and tiny tracking-style images, preserving BlockNote's ordinary single-click image selection path.
 - The `/` slash menu remains the supported path for markdown-safe block transformations such as headings, quotes, and list blocks. Tolaria filters out BlockNote's toggle-heading and toggle-list variants because those do not map cleanly to the markdown note model.
 - The block-handle side menu keeps only actions that survive Tolaria's markdown round-trip. Delete and table-header toggles remain available; BlockNote's `Colors` submenu is removed because block colors are not part of Tolaria's supported markdown surface.
 - `useNoteWikilinkDrop()` is the shared editor-drop abstraction for dragging note rows into either editor mode. It reads the existing note-retargeting drag payload, resolves the vault-relative stem, and inserts a canonical `[[wikilink]]` without hijacking unrelated plain-text drags.

 ### Product Events
 - **File previews** — `file_preview_opened`, `file_preview_action`, and `file_preview_failed` report only preview/action categories such as `image`, `pdf`, `unsupported`, `open_external`, `copy_path`, and `reveal`.
+- **Inline image lightbox** — `inline_image_lightbox_opened` records that a rich-editor inline image was opened from double-click, without sending note paths, image URLs, alt text, or file names.
 - **AI agent sessions** — `ai_agent_message_sent`, `ai_agent_message_blocked`, `ai_agent_response_completed`, `ai_agent_response_failed`, and `ai_agent_permission_mode_changed` use only agent ids, permission modes, counts, and coarse status categories.
 - **All Notes visibility** — `all_notes_visibility_changed` records only the toggled category and enabled state.

 - **Sidebar** (150-400px, resizable): Top-level filters (All Notes, Changes, Pulse), saved Views, collapsible type-based section groups, and a dedicated folder tree. The title bar exposes Back/Forward buttons wired to the same note navigation history as the command palette, menu accelerators, and mouse navigation buttons. The folder tree starts with a vault-root row labeled from the opened vault path, shows root-level files when selected, and nests user-created folders plus default vault folders such as `attachments/` and `views/` underneath it; only the dedicated `type/` directory stays hidden because note types already have their own sidebar section. Saved Views persist a top-level YAML `order` field in each view file and use the same ordered-list mental model as Types: pointer users can drag the existing view row, while keyboard users can use command-palette move actions. The folder tree supports inline folder creation and rename, exposes a right-click menu for rename/delete plus filesystem reveal/copy-path actions on mutable folders, and auto-expands ancestor folders when the current selection or rename target is nested. Type sections and folder rows also act as note drop targets: dropping a note on a type updates its `type:` frontmatter, while dropping it on a folder runs the same crash-safe move path as the command palette flow. Each type can have a custom icon, color, sort, and visibility set via its `type: Type` document; new type documents created by Tolaria are written at the vault root.
 - **Note List / Pulse View** (200-500px, resizable): When a section group, filter, or saved view is selected, shows filtered notes with snippets, modified dates, status indicators, and per-context note-list controls. When `selection.kind === 'entity'`, the same pane enters **Neighborhood** mode: the source note is pinned at the top as a normal active row, outgoing relationship groups render first, inverse/backlink groups follow, empty groups stay visible with `0`, and duplicates across groups are allowed when multiple relationships are true. Plain click / `Enter` open the focused note without replacing the current Neighborhood, while Cmd/Ctrl-click and Cmd/Ctrl-`Enter` pivot the pane into the clicked note's Neighborhood. Folder-backed lists also show non-Markdown files: previewable image and PDF binaries get file indicators and open in the editor pane, while unsupported binaries remain muted instead of auto-launching an external app. Saved views reuse the same sort and visible-column controls as the built-in lists, and those changes persist back into the view `.yml` definition (`sort`, `listPropertiesDisplay`). When Pulse filter is active, shows `PulseView` — a chronological git activity feed grouped by day.
-- **Editor** (flex, fills remaining space): Single note open at a time (no tabs — see ADR-0003). Breadcrumb bar with word count and rich-editor width toggle, BlockNote rich text editor with wikilink support, Markdown-compatible inline/display math rendering, first-class Mermaid diagram blocks, markdown-safe formatting controls, and schema-backed fenced code block highlighting via `@blocknote/code-block`. Can toggle to diff view (modified files), raw CodeMirror view, or a wide rich-editor reading surface with preserved side margins; raw CodeMirror remains full-width and unaffected by note width mode. Binary image and PDF files render through `FilePreview` as ordinary vault files using Tauri asset URLs; external-open actions call `open_vault_file_external` so the target is validated against the active vault before the native default app opens it. Unsupported/broken binaries show explicit fallback states and keyboard focus returns to the note list on `Escape`. Decomposed into `Editor` (orchestrator), `EditorContent`, `FilePreview`, `EditorRightPanel`, `SingleEditorView`, with hooks `useDiffMode`, `useEditorFocus`, and `useEditorSave`, plus the `useRawMode`/`RawEditorView` pair for markdown source editing. Rich BlockNote input and raw CodeMirror input both route typed `->`, `<-`, and `<->` through the shared `src/utils/arrowLigatures.ts` resolver so arrow ligatures stay consistent across mode switches while escaped ASCII sequences remain literal. Navigation history (Cmd+[/]) replaces tabs.

 - **Inspector / AI Agent** (200-500px or 40px collapsed): Toggles between Inspector (frontmatter, relationships, instances, backlinks, git history) and AI Agent panel (the selected CLI agent with tool execution). The Sparkle icon in the breadcrumb bar toggles between them. Per-note `icon` is a suggested Inspector property and the command palette's "Set Note Icon" action opens that field directly. When viewing a Type note, the Inspector shows an **Instances** section listing all notes of that type (sorted by modified_at desc, capped at 50).
 
 Panels are separated by `ResizeHandle` components that support drag-to-resize.
