QDev 1.0 — huge files, on-device AI, and local files that just open.

• JSONL (newline-delimited JSON) is now a first-class format: open a .jsonl
  file and every record is browsable in the tree, table, and columns views.
• AI on very large files: ask and search now work on huge JSON/JSONL (hundreds
  of MB to multi-GB). Answers are grounded on the whole file, not just the
  first screenful — so fields that only appear deep in the file are found. As
  always, your data never leaves the device; only field names and shapes inform
  the AI.
• Exact counts and fast navigation on huge files: the status bar shows the true
  record count instead of a truncated estimate, and jump-to-end/line is a quick
  seek instead of a freeze.
• Large local files open from disk: opening a big local .json in the browser
  now shows it in QDev instead of Chrome's raw text; a file too large to render
  as a page offers a one-click drop-to-open that streams it at any size.
• Faster on big files: snappier opening, smoother keyboard navigation, and
  quicker repeated queries.
• A file too large for a browser tab (over ~4 GB) now shows a clear message
  instead of crashing the tab.
• On-device AI with no setup: if your browser ships Chrome's built-in model
  (Gemini Nano), QDev answers entirely locally — no key, no account. Clearer
  Ollama setup guidance when a local daemon blocks the browser.
• Under the hood: the viewer is now a standalone, AI-free core with optional
  plugins — faster to load and fully open-source. No change to how you use it.

Two new ways to explore documents, an editor-style menu bar, and a fix that
keeps you signed in.

• New Table view: browse an array of objects as a sortable table — click a
  column header to sort, double-click a row to jump to it in the tree.
• New Columns view: navigate nested data Finder-style, column by column, with
  arrow-key navigation and a detail panel showing each value's type and path.
• New menu bar (File / View / Settings / Help) replaces the view tabs: open and
  save files, switch views with ⌘1–⌘6, search every menu command from Help, and
  check version and account info in the new About dialog.
• Fixed: the extension no longer shows you as signed out (hiding your Pro
  features) a few hours after signing in — your session now renews itself in
  the background, and a brief network hiccup can no longer flip you to
  signed-out either.
• Fixed: asking "how many match?" on very large documents now returns an exact
  count instead of silently undercounting when the result list was truncated.

AI on large documents, smarter recovery from oversized results, and an opt-in
program to help improve query accuracy.

• AI ask and search suggestions now work on large documents. Previously
  anything over 64 MB showed "AI query isn't available for very large
  documents" — now questions are grounded on a compact structural sample and
  queries stream over the file, so even multi-hundred-MB documents are
  askable. As always, your data never leaves the device — only field names
  and shapes inform the AI.
• Questions whose answers are too large to display (over 25 MB) now return a
  bounded preview instead of failing with an error.
• New in settings: optionally share de-identified question + schema data from
  your queries to help improve jq accuracy — off by default, with billing
  discounts for Pro subscribers who opt in.
• A polished loading screen while large files open.
