v0.8.0

Added

• Compliance by OS. The Compliance tab now has a "Compliance by OS" section — a
  per-OS compliance bar chart and table (devices, compliant, compliance %, pending
  Critical/Important, aged past SLA), grouped by each device's reported OS — so a
  lagging OS version is easy to spot alongside the existing per-organization view. Like
  the rest of the tab it reflects the selected device scope's whole pending backlog. The
  Excel export gains a matching Compliance by OS sheet, and the HTML executive
  report a matching "Compliance by OS" section (bar chart + table).

Changed

• Clearer data scope across the result tabs. The results area now groups the tabs
  by scope tier — Filtered results (Patches, Failures), which honor every patch
  filter, and Fleet health (Compliance, Needs Reboot), which reflect the whole
  pending backlog for the selected device scope and ignore the patch filters. Each tab
  leads with a banner spelling out exactly what it shows and which filters apply, and a
  read-only chip row summarizes the filters behind the current result. On a Fleet-health
  tab the patch-tier chips grey out (they're ignored there) and the patch-filter controls
  hide entirely, so the view never implies a filter is shaping numbers it doesn't.

Fixed

• Filters panel on mobile. Removed the dead space below the "Filters" title
  (the heading is now aligned with the Show/Hide toggle) and made the filter rows
  stack cleanly on narrow / phone-width viewports, where the fixed label and control
  widths previously crowded the screen.
