📢 dn has become TDF — new client, new format, new home

[crisdosaygo]

dn is growing into something new

DownloadNet (dn) — the offline web archiver that intercepted responses inside Chrome's fetch cycle over CDP — was the seed of TDF (Tree Document Format):

• 🌱 Tree Grower captures live browsing sessions into portable .tdf archives — growing dn's Chrome-only CDP interception into a multi-browser architecture (Chrome, Firefox, Chromium family) over WebDriver BiDi/CDP, with active, blocking capture. No re-fetching; the browser stays the source of truth.
• 🌳 Tree Player opens and replays .tdf archives offline — free for everyone.
• 📦 A .tdf archive is a single compressed (optionally encrypted) SQLite file with indexed, deduplicated bodies — built for instant replay and easy sharing.
• 🦀 Both are native Rust apps with a GUI. No Node, no npm, no localhost server.

What this means for this repo

• The new product line is closed-source; this repo is now the public home of TDF (docs, release pointers, announcements) and the permanent archive of dn.
• The entire dn codebase and its README are preserved, unmodified, under legacy/, still under its PolyForm Strict license. The final release stays available: v4.5, and npm i -g downloadnet continues to work.
• dn is no longer developed or supported. All open issues and PRs have been closed as part of this transition — not because the reports weren't valued, but because the codebase they describe is now frozen.
