v1.1.1

Fixed

• Tray companion name — the Windows tray tooltip and menu header still
  rendered the old product name ("9Router Go (Stopped)", "9Router Go (Port
  20128)", …) on released v1.1.0 binaries. The state titles in internal/tray
  now say 9RouterX in every state (Running / Stopped / Port conflict /
  Unknown); no user-visible "9Router Go" string remains in the tray tree.
• Tray and executable icons — the tray icon and the Windows executables
  still carried the old 9router-go artwork. tools/icongen (new) builds the
  multi-size .ico (16/24/32/48/64/128/256 px frames, 32-bit BGRA + AND
  mask) straight from the 9RouterX logo (web/public/logo-9routerx.png);
  cmd/9routerx-tray/tray.ico is regenerated (the go:embed'd runtime tray
  icon) and both 9routerx.exe and 9routerx-tray.exe now embed it as a
  Windows resource (rsrc_windows_amd64.syso, generated with go-winres and
  linked automatically by go build), so Explorer, the taskbar and the tray
  all show the new icon. Regenerate after a logo change with make icons.
• Auto Update path — version.json advertised 1.1.0 without a sha256,
  and since #72 a digest-less manifest is refused by design, so every install
  fell through to the GitHub Releases API — which returned HTTP 500 for some
  users, ending in "manifest error (manifest carries no sha256 for 1.1.0),
  github releases error (github releases HTTP 500)". The release workflow now
  publishes per-platform sha256s (plus per-platform downloadUrls) into
  version.json from SHA256SUMS.txt at release time, and checkManifest
  selects the digest for the running platform, so the manifest alone carries
  everything an install needs and the release-API fallback is no longer on
  the critical path.
