Release v1.2.0

Added

• Lossless compression for WebP, AVIF, and JXL output (--lossless).
• Encoder effort/speed control for WebP, AVIF, and JXL (--effort).
• --combine to merge multiple inputs into a single archive (issue #21).
• Settings profiles in the GUI, also reusable from the CLI via --profile (issues #34, #58).
• --zip-level to set the CBZ deflate compression level (issue #48).
• --dpi to control the document rendering resolution (issue #52).
• --no-upscale to skip enlarging images already smaller than the requested size.
• Multi-language GUI.
• GUI file list as a sortable table.
• GUI page-by-page preview (page spin) and a cover preview in the open file dialog.
• GUI "Command" button showing the equivalent command line (issue #33).

Changed

• Replaced the archive backend (go-unarr) with the pure-Go mholt/archives, adding RAR5 and removing the unarr cgo dependency.
• Removed the godbus portal dependency; the GUI file dialog now routes through the XDG portal via IUP.
• Reworked the GUI: reorganized the Input tab with more tooltips, gradient preview background, and Convert turns into Cancel while a job runs.

Fixed

• Comic chapters in numbered subfolders no longer overwrite each other (issue #50).
• CLI flags can now be passed in any order, including after the file and directory arguments, and a missing output directory is created automatically (issue #41).
