Baixar SageThumbs 2K 3.0.0 per a Windows

## What's changed

### Added

- **A "Join our Discord" button on the sign-in banner.** Questions, ideas, or a hello: the
LunarWerx Discord is where we are. The button opens a LunarWerx page that forwards to the
current invite, so the link in the app never goes stale.
- **Save the video frame you are looking at.** The Quick preview's Save button now works on a
video and writes the frame at the current position, and a right-click on a video-only selection
offers "Save frame as image" instead of the picture verbs that never applied to it.
- **Screen readers can use the Settings window.** Every category in the left-hand rail now
reports its name and which one is selected, so Narrator and NVDA announce where you are.
- **A hex view for files nothing can render.** An unknown binary shows a classic hex dump
instead of a bare info card, truncated with a note rather than trying to read the whole file.
- **Folders show their total size** in the Quick preview, and say "more than" instead of a wrong
number when the folder is too large or too deep to finish counting quickly.
- **A per-extension Quick preview blocklist** on the Quick preview settings page: list the
extensions you never want previewed. Empty by default, and separate from the File types page.
- **Pressing Space on something that is not a file now says so.** Recycle Bin, This PC and other
virtual items used to do nothing at all.
- **HDR PNGs render correctly.** A PNG carrying the `cICP` colour chunk with a PQ or
HLG transfer (what recent HDR tools write) is now converted to linear light and
tone-mapped the way EXR and Radiance files already are, instead of being shown as a
washed-out picture with the wrong curve. Ordinary PNGs are untouched.
- **Rename with pattern.** A new entry in the Rename submenu opens a small dialog: type a
pattern such as `{name}_{n:3}` (placeholders for the name, extension, a padded counter,
the capture date and the pixel size), optionally find and replace text, watch the live
preview, and rename the selection in one go. Nothing is ever overwritten.
- **Set as lock screen**, beside "Set as wallpaper", for any format SageThumbs can decode.
- **`st2k upload <file>`** uploads through the same hosts the screenshot editor uses and prints
the URL (`--copy` also puts it on the clipboard).
- **The Quick preview's toolbars are keyboard-reachable.** Tab moves into the caption
toolbar and the video controls, arrows move along them, Enter or Space presses, Escape
returns to the content; the focused button shows a ring.
- **Print from the Quick preview.** A print button on the caption toolbar (or **Ctrl+P**)
sends the image, the PDF page or the animation frame you are looking at to the standard
Windows print dialog, fitted to the page.
- **Watermark in the Convert dialog.** Tick "Watermark", choose an image, and pick a corner
(or the centre), a size as a percentage of the picture and an opacity; it is applied after
the resize and before the encode, for every output format including the ImageMagick ones.
- **Three more wallpaper placements: Fill, Fit and Span**, alongside the existing Stretch,
Tile and Center, in the "Set as wallpaper" menu.
- **Sort by date taken.** A new "Sort into folders Γû╕ By date taken" verb moves each selected
image into a `YYYY-MM-DD` folder named from its EXIF capture date; a file with no capture
date is left where it is.
- **Copy as data URI.** A new "Copy as data URI" verb base64-encodes the selected image and
copies a `data:<mime>;base64,...` URI to the clipboard as text, ready to paste into CSS,
HTML or JSON.
- **Retry only the files that failed, from the command line or from the failure report.** After
a batch that only partly succeeded, `st2k batch --retry-from report.json` re-runs exactly the
files a saved `--json` report lists as failed, with whatever options you give it, and reports
the retry the same way so a second retry can follow on. In the app, the Convert dialog's
failure report now has a "Retry failed" button that runs those same files again with the same
settings and shows the result the same way.
- **A tester's checklist for installed, portable, admin and multi-user setups ships with the
source.** A documented scenario matrix and a one-command script now cover storage mode
(installed or portable), running as standard or as an administrator, who installs versus who
runs the app, and multiple sessions on the same machine (including Remote Desktop), so that
ground can be checked the same way every time instead of being re-worked out from scratch.
- **The format list now explains HOW each file type's thumbnail is made, not just that it's
supported.** The Settings file-types list has a new "How" column (full decode, embedded
preview, cover art, cover or first page, video frame, or contents of the archive), the
`st2k formats --json` output carries the same detail for scripts and the website, and
`st2k doctor` reports which formats depend on an optional Windows codec and whether it's
actually installed on your machine.
- **The sync and licence status lines are more honest about what is actually happening.**
Settings Γû╕ Data & Backup now shows a plain "Offline" state when a sync attempt could not
reach the server at all, instead of describing it the same way as a save that reached the
server and was rejected. Disconnecting an account now tells you if the copy stored in your
account could not be deleted, rather than always saying it was. On the Licence page, a
machine running on an offline certificate now gets an early warning as that certificate's
own expiry approaches, separate from the ordinary "Licensed" line.

- **The command line and MCP tools gained a `cbz` command, folder recursion, and richer batch
info.** You can now combine a folder of images straight into a comic-book archive (`.cbz`)
from the command line or through the MCP tool used by AI assistants and scripts, matching
the existing PDF command. Batch jobs can now recurse into subfolders with a `--recurse` flag,
and a new batch "info" option returns details for every file in one call, including proper
tag data (artist, album, title, and more) for audio files.

- **The built-in diagnostics tool can now spot when another program has taken over your
thumbnails, and export its findings as a file you can share.** Running SageThumbs 2K's
doctor/diagnostics check now detects when a different program's icon handler has silently
replaced SageThumbs' own for a file type, and shows which handler took over. Its report can also be
exported as a single zip file, including the relevant tail of the error log, handy when
asking for help.

- **A Save button in the preview window.** Viewing a PDF page or an animated image and want to
keep just that page or frame? A new Save button (and the Ctrl+S shortcut) saves the page or
frame you're currently looking at as a PNG image.

- **Batch, PowerShell, and Perl script files are now colour-highlighted in the text preview.**
Previewing a `.bat`, `.ps1`, or Perl script now shows proper syntax colouring, including files
that only identify their type through a `#!` line at the top rather than their extension.

- **Ctrl+U now triggers "Upload & copy" in the screenshot overlay.** Uploading a screenshot and
copying its link no longer requires reaching for the mouse.

- **The eyedropper tool now tells you when a colour reading is approximate.** Picking a colour
from an HDR display now shows a small note explaining that the value is sampled from the
tone-mapped (SDR) picture, since a true HDR value can't be read this way.

- **After SageThumbs updates itself, a notification offers to refresh your thumbnails right
away.** Previously you'd only see the new thumbnails once Explorer's cache naturally expired;
a click on the notification now refreshes them immediately.

- **The installer now asks how you will use SageThumbs 2K: personal (free) or business.**
Personal, non-commercial use stays free with every feature, exactly as before. Business and
other commercial use requires a commercial licence under the PolyForm Noncommercial license
the app has always shipped with; the installer now says so plainly instead of leaving it in
the licence text nobody reads. Your answer is remembered across updates, and changing it
means reinstalling. Nothing about thumbnails, previews, or any feature changes either way.

- **A Licence page in Settings for redeeming a business seat key, with a background check
that keeps it current.** Enter the seat key you were given (`esk_...`) under Settings Γû╕
Licence and the copy is on record as licensed; personal use needs nothing and stays exactly
as it was. A business copy has every feature from the moment it's installed, key or not, it
just reminds you to add one: a notice when you launch it, and a strip on the Settings page
that stays until you do. The check that keeps a redeeme
