Sækja BertBrowser 1.1.2

A small release: two annoyances in the sidebar tree and the size UI, and the last of the on-demand folder-size machinery removed now that every folder's size comes from the index.
Installed copies update themselves. New installs: BertBrowser-win-Setup.exe below, or winget install RobWalsh.BertBrowser.
Fixes
- Clicking a folder in the sidebar no longer makes it shut and spring back open. A single click on a folder row still opens or closes it, but which way it goes now depends on where the click is taking you: clicking an open folder you're already in closes it, while clicking an open folder you're navigating to leaves it open — collapsing that one was immediately undone by the reveal the same click kicked off, which read as a flicker.
- No more progress bar flashing in the Size column. Folder sizes come from the index, so there was nothing to wait for.
Folder sizes
- "Compute size" is gone from the context menu, along with the Calculate button in Properties. Every folder on an NTFS volume is sized as a side effect of the search index pass, so the numbers are already there — an on-demand scan only competed with the indexer for the same answer.
- A folder with no size yet now says "Not indexed yet" rather than "Not yet calculated", which is what it actually means: a still-indexing or non-NTFS volume, never a size of zero.
Elsewhere
- The Show hidden items toggle has left the title bar; it's a preference you set once, and it lives in Settings.
- winget submissions are now opened automatically by the release workflow, so winget install RobWalsh.BertBrowser should track releases more closely.
