* fix(ui): resolve folder download URL against document.baseURI for subpath support
When Hermes WebUI is served behind a reverse proxy with a path prefix
(e.g. /hermes/), the right-click → "Download Folder" context menu option
navigates to a root-absolute URL (/api/folder/download?...), which resolves
to the server origin instead of the proxy mount point, causing a 404.
This matches the pattern already used by the workspace.js route helper
refactored in v0.52.41 (commit 1a64d7d3).
* CHANGELOG: folder-download subpath baseURI fix (#6227)
