Release v0.5.3

Follow-up to v0.5.0, which introduced the integrity model redesign and Integrity page. See the v0.5.0 changelog entry for full details on the new integrity architecture, hash version tracking, review system, and the removal of the alerts system.

Added

• Scan summary bar on Browse page: Display scan metadata (date, file count, folder count, total size, change icons) as a title bar above the tree/folder/search content area. Clickable to open full scan detail sheet
• Scan list change icons: Replace text-based change summaries in the calendar scan picker with the shared ChangeIcons component for visual consistency with History and Home pages
• Independent scroll regions on Browse page: Tree/folder/search and item detail panel scroll independently, preventing detail panel from scrolling out of view. Detail panel always visible with empty state placeholder
• Browse link in scan detail sheet: Navigate from scan details to Browse page viewing that scan. Hidden when already on Browse page

Changed

• Browse filter control: Move change type filter from a full-width bar into a popover triggered by a button with a ChangeDots-style 2x2 grid indicator, reclaiming vertical space on the Browse page
• Scan detail sheet redesign: Match ItemDetail styling (header, fonts, layout). Add scan duration, scan options, integrity table (new/total suspect hashes and validation errors), error display. Use shared ChangeIcons and icon patterns from Browse/History pages
• Trends page chart clicks: Open scan detail sheet instead of navigating directly to Browse, with browse link available from the sheet

Fixed

• Scan detail sheet on Roots page: Remove references to deleted alert_count column that caused the scan detail sheet to fail with "Internal Server Error" when clicking on scan info
