v5.0.18 - Stable

Added

• WebUI: Network scan (“Search network”) for discovering devices across local subnets and VLANs, including progress, results, and an Add target flow.
• WebUI: Bulk actions (Enable, Disable, Test, Delete, Clear selection).
• WebUI: Target modals for Information and Edit (update targets without deleting and re-adding).
• WebUI: Logs viewer with level filters (INFO / WARN / ERROR), copy functionality, and exports (CSV / XLSX / PDF).
• WebUI: Status snapshots (small recent history dots) per target.
• CLI: Additional read/edit commands to support WebUI features.
• Installer: Simple interactive install / update / uninstall wizard for hosted scripts.
• Debugging: Backend diagnostics for “empty table” and state-source issues
  (systemd journal + /var/lib/interheart/webui_debug.log) and /api/debug-state.

Changed

• Status semantics and labels clarified in the UI
  (e.g. OK, HEARTBEAT FAILED, NOT RESPONDING, STARTING…, DISABLED).
• Disabled targets now render with a neutral grey status indicator (instead of warning yellow).
• Heartbeat failures retry aggressively (every 5 seconds) to recover as quickly as possible.
• WebUI action and refresh behavior tuned to avoid interrupting user interaction
  (menus no longer auto-collapse due to state refresh).
• Layout and UX improvements across tables, modals, and controls
  (more consistent spacing, widths, and readability).
• WebUI systemd service adjusted for local-operations usage so it can read logs and write runtime data without sudo prompts.

Fixed

• WebUI: Targets no longer require Run now before appearing after opening the page.
• WebUI: Prevent targets from briefly appearing and then disappearing on first load
  (no premature table clearing before the first state poll).
• WebUI: Run now modal no longer gets stuck in a false running state
  (finished processes are reaped; zombie PIDs are treated as completed).
• WebUI: Correct runtime status source is now used
  (runtime table instead of legacy state data).
• WebUI: Actions menu stability fixes
  (enable/disable visibility, alignment, and no hidden dropdowns when few rows exist).
• WebUI: Sorting and header rendering regressions fixed
  (stable header row and correct sort indicators).
• WebUI: Network scan reliability improvements
  (better subnet discovery, improved progress reporting, cancel / rescan behavior).
• WebUI: Log formatting fixes
  (clean timestamps and reliable exports).
• Permissions: Resolved issues writing run output files and reading systemd journal logs without interactive sudo prompts.
