Dench workspace: Tiptap markdown editor, subagent sessions, and error surfacing
── Tiptap Markdown Editor ──

- Add full Tiptap-based WYSIWYG markdown editor (markdown-editor.tsx, 709 LOC)
  with bubble menu, auto-save (debounced), image drag-and-drop/paste upload,
  table editing, task list checkboxes, and frontmatter preservation on save.
- Add slash command system (slash-command.tsx, 607 LOC) with "/" trigger for
  block insertion (headings, lists, tables, code blocks, images, reports) and
  "@" trigger for file/document mention with fuzzy search across the workspace
  tree.
- Add ReportBlockNode (report-block-node.tsx) — custom Tiptap node that renders
  embedded report-json blocks as interactive ReportCard widgets inline in the
  editor, with expand/collapse and edit-JSON support.
- Add workspace asset serving API (api/workspace/assets/[...path]/route.ts) to
  serve images from the workspace with proper MIME types.
- Add workspace file upload orkspace/upload/route.ts) for multipart
  image uploads (10 MB limit, image types only), saving to assets/ directory.
- Add ~500 lines of Tiptap editor CSS to globals.css (editor layout, task lists,
  images, tables, slash command dropdown, bubble menu toolbar, code blocks, etc.).
- Add 14 @tiptap/* dependencies to apps/web/package.json (react, starter-kit,
  markdown, image, link, table, task-list, suggestion, placeholder, etc.).

── Document View: Edit/Read Mode Toggle ──

- document-view.tsx: Add edit/read mode toggle; defaults to edit mode when a
  filePath is available. Lazy-loads MarkdownEditor to keep initial bundle light.
- workspace/page.tsx: Pass activePath, tree, onSave, onNavigate, and
  onRefreshTree through to DocumentView for full editor integration with
  workspace navigation and tree refresh after saves.

── Subagent Session Isolation ──

- agent-runner.ts: Add RunAgentOptions with optional sessionId; when set, spawns
  the agent with --session-key agent:main:subagent:<id> ant so
  file-scoped sidebar chats run in isolated sessions independent of the main
  agent.
- route.ts (chat API): Accept sessionId from request body and forward it to
  runAgent. Resolve workspace file path prefixes (resolveAgentWorkspacePrefix)
  so tree-relative paths become agent-cwd-relative.
- chat-panel.tsx: Create per-instance DefaultChatTransport that injects sessionId
  via body function and a ref (avoids stale closures). On file change, auto-load
  the most recent session and its messages. Refresh session tab list after
  streaming ends. Stop ongoing stream when switching sessions.
- register.agent.ts: Add --session-key <key> and --lane <lane> CLI flags.
- agent-via-gateway.ts: Wire sessionKey into session resolution and validation
  for both interactive and --stream-json code paths.
- workspace.ts: Add resolveAgentWorkspacePrefix() to map workspace-root-relative
  paths to repo-root-relative paths for the agent process.

── Error Surfacing ──

- agent-runner.ts: Add onAgentError callback extraction helpers
  (parseAgentErrorMessage, parseErrorBody, parseErrorFromStderr) to surface
  API-level errors (402 payment, rate limits, etc.) to the UI. Captures stderr
  for fallback error detection on non-zero exit.
- route.ts: Wire onAgentError into the SSE stream as [error]-prefixed text
  parts. Improve onError and onClose handlers with clearer error messages and
  exit code reporting.
- chat-message.tsx: Detect [error]-prefixed text segments and render them as
  styled error banners with alert icon instead of plain text.
- chat-panel.tsx: Restyle the transport-level error bar with themed colors and
  an alert icon consistent with in-message error styling.
