LinkUnzip 1.0.0

The first public release.

Added

• The File List: folders with breadcrumbs, checkboxes, a Filter box that searches every name,
  select all or none, live totals; files you leave out are not downloaded. Pattern... keeps
  the glob filter (*.dll, docs/*) for power users, with a button that clears it.
• Browse... opens the Windows folder picker (linkunzip debug pick-folder tries it from the
  command line).
• Resume: a stopped or failed job can run again into the same folder and skips the files that
  are already finished and verified (CRC-32 and size); its progress bar carries on from where it
  stopped. A Resume button on stopped and failed jobs; --overwrite on the command line
  extracts everything again.
• Friendly errors with a Copy details button: a link that opens a web page instead of the
  file, a login that is needed, an expired link, a file that is gone, not a zip, a server error,
  a full disk, a folder that can't be written, a server that can't be reached.
• "All N files verified" on the done screen.
• The helper reports its version, protocol and features; the extension offers an update when the
  helper is too old, and keeps working with it meanwhile.
• Light and dark themes: follows Windows, or choose with the sun/moon button or
  Settings > Appearance. Visible keyboard focus, keyboard use of the file list, screen reader
  labels.
• A Cancel button on the ready screen.
• The Cost Analysis follows the files ticked in the File List (files to write, to download, a
  normal download, free space).
• Before asking Chrome for a site, the login card says where the cookies go: only to the helper on
  this PC, and from there only to that site.
• Release workflow for GitHub Releases (installer, store zip, SHA256SUMS.txt) with an optional
  code-signing step.
• Open-source repository: GPL-3.0-or-later licence, contributing guide, security policy, issue
  templates, privacy policy, CI and a release workflow.

Changed

• New look: the LinkUnzip logo everywhere (extension, helper, installer), a dark header with
  LINKUNZIP, Cost Analysis and the File List in one panel, the main buttons always in view, a
  status bar, and the zinc colour palette.
• No "read and change all your data on all websites" warning at install: public links need no
  site permission, and LinkUnzip asks for a site only when a download needs your login there
  (or once for every site, if you turn that on in Settings).
• "Downloaded" now includes the zip's index, also shown on its own.

Download

• linkunzip-setup.exe: the Windows helper (installs just for you, no administrator rights).
  The extension's setup page downloads it for you.
• linkunzip-extension-1.0.0.zip: the extension as submitted to the browser stores.
• SHA256SUMS.txt: checksums. Compare with Get-FileHash .\linkunzip-setup.exe -Algorithm SHA256.

This build is not code-signed, so Windows SmartScreen may warn about an unknown publisher: choose More info, then Run anyway, after checking the SHA-256.
