[Weidows]

Description

Build GUI pages for the five one-shot services: ZipCrack, Diff, Media, Extract, GMM.

ZipCrack Page

• File picker for archive (.zip/.7z/.rar/.tar.gz)
• Password dictionary file selector (optional, defaults to ~/.config/wutils/password-dict.txt)
• "Start Crack" button with cancel
• Real-time progress: password tested/sec, elapsed time, current password
• Result display: found password or "not found" with completion time
• Drag-and-drop support for archive file

Diff Page

• Two file input areas with file picker buttons
• "Compare" button
• Side-by-side result display:
  • Left panel: "Missing in A" (items only in B)
  • Right panel: "Missing in B" (items only in A)
• Copy-to-clipboard for each result set
• Line count summary

Media Group Page

• Directory picker for input folder
• Customizable clustering parameters:
  • Time threshold (hours, default: 12)
  • Distance threshold (km, default: 1)
• "Start Grouping" button
• Progress indicator (files processed / total)
• Result display: cluster list with file counts, total size
• Preview images per cluster (thumbnails)
• Warning if output will be large

Extract Page (Subdir-Extracter)

• Directory picker for root path
• Mode selector: AutoCheck / Overwrite / Skip
• "Extract" button
• Log output showing what was moved/renamed/removed
• Preview mode: show what would happen without executing

GMM Page

• Two tables: GOPROXY mirrors and GOSUMDB mirrors
• Each row shows: name, URL, latency (ms), status (✅/❌)
• "Test All" button — runs speed test on all mirrors
• Click on a row to set as active proxy/sumdb
• "Current" display showing active GOPROXY and GOSUMDB env values
• Copy config command to clipboard (e.g., go env -w GOPROXY=...)

Acceptance Criteria

• Each page can invoke its corresponding Go service
• Results display correctly in the UI
• Error states are handled gracefully with user-friendly messages
• File/directory pickers work via Wails native dialog
