Add disk space display to footer

[Copilot]

Displays total, free, and used disk space in the footer when scanning drives or folders.

Implementation

• Disk space retrieval (app/js/radar.js)

  • New getDiskSpaceInfo() using existing systeminformation.fsSize()
  • Longest-prefix matching for nested mount points (e.g., /home vs /)
  • Path normalization for Windows backslash handling
  • Error callback with fallback to "Disk info unavailable"

• UI integration (app/index.html, app/css/style.css)

  • Added disk_space_info span to footer toolbar
  • Positioned before breadcrumb trail, non-intrusive

Display format

Total: 144.26 GB | Free: 91.24 GB | Used: 53.01 GB (36.75%)

Technical notes

• Uses existing systeminformation dependency (v5.30.7) - cross-platform compatible
• Mount point matching handles nested filesystems correctly by selecting longest match
• Null-safe handling for missing usePercent property

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• esm.ubuntu.com
  • Triggering command: /usr/lib/apt/methods/https /usr/lib/apt/methods/https (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)

Comments on the Issue (you are @copilot in this section)

@zz85 also on my TODO ;) there are cross platforms issues with this but certainly something for me to add.. @zz85 I'm still slightly holding off on this one... Ideally I would love to use https://github.com/jduncanator/node-diskusage, but this might have to wait till I slightly understand how the native bindings work in electron. Otherwise [this](https://github.com/jduncanator/node-diskusage) might be simplier to use but has no support for windows...
