v0.19.0

Added

• wtm-service cleanup removes RustWTM's blocked-program entries and its
  firewall rules; the MSI runs it on a full uninstall and
  wtm-service uninstall (used by uninstall.ps1) runs it too.
• The MSI asks a running RustWTM window to close before it removes or
  replaces files.
• wtm list, wtm info and wtm ports take --json.
• Snapshots say whether a process is suspended and whether per-process
  network traffic was measured; the service status carries the error of a
  configuration file it could not load (IPC protocol 14).

Fixed

• Uninstalling left blocked programs pointing at a deleted rustwtm.exe and
  RustWTM's firewall rules in place.
• Remove limits reported success for a process RustWTM had not limited; it
  now says so.
• Resuming a process suspended several times left it frozen; resume now
  undoes every suspension.
• A client could suspend itself through the service and freeze.
• An invalid configuration at service start was only logged to file; it is
  now an event and part of the status.
• A priority or efficiency mode set by hand was undone when the governor
  later rolled back its own change.
• The hardware sensor helper kept running after the Sensors tab was closed;
  it now stops after 30 s without requests unless a fan profile is active.
• wtm list/top and the MCP server no longer present unmeasured
  per-process network traffic as 0 B/s. The MCP server measures CPU, disk
  and network over a fresh window instead of since the previous call (or
  uses the service's sample), and its control tools accept the
  create_time from list_processes to refuse a reused PID.
• The stale 0.13.0 review is no longer installed by the MSI.
• An Explorer window on a folder named RustWTM stopped RustWTM from
  starting; the single-instance check now uses a per-session lock and finds
  the running window by its program.
• Restart as administrator could end with no RustWTM running; the new copy
  waits for the old one to exit.
• With a newer service the window advised installing an older version; the
  advice and the status badge now name the actual problem.
• Events were listed twice after reconnecting to the same service.
• Ending processes or testing Telegram no longer holds up monitoring
  updates while the request runs.
• A RustWTM hidden in the tray now quits when Windows or an installer asks
  it to.
• Raw error codes on a service restart and command-line wording in the
  window's error messages are replaced by plain messages.

Changed

• The window draws with OpenGL instead of wgpu: about 250 MB less memory
  and a 30% smaller program.
• Visual pass: readable status colours and visible bar tracks and text
  fields in the light theme; full column headers in every language with
  right-aligned numbers; one card title and sortable-header style; loading
  and empty states with text; a stale-data banner that dims the page; the
  data age on the subtitle line; a gear icon for Settings; labels before
  controls in the power and cooling forms; translated priority, startup and
  finding names; level filter and sorting in Events; a ⋯ menu for the
  busiest apps' actions.
• Processes marks suspended processes and shows "—" for network traffic
  that is not measured; Settings and the Overview show why the service
  could not load config.toml.
• Ctrl+Tab and Ctrl+Shift+Tab switch pages, Ctrl+F searches Services,
  Network and Ports, and Esc closes the process details.
• The More below hint also shows on Performance, About and the process
  details.
