kvmshare v0.8.8

Portable kvmshare release.

The bootstrap scripts verify every download against SHA256SUMS (with GitHub's per-asset digests as fallback) before executing anything, then hand off to the Go installer: archive download + verify + atomic binary apply + desktop integration (udev input access on Linux; shortcuts, elevation tasks, firewall on Windows). Pin a version: sh install.sh v0.8.8 / install.ps1 -Tag v0.8.8. Uninstall: sh install.sh --uninstall.

In this release

• Terminal bootstrap installers (sh / PowerShell / npx) — the no-clicks path for unsigned binaries
• Security hardening: UDP cursor stream bound to the TCP handshake's IP (forged beacons/crossings from another machine rejected), frame-length caps enforced before buffering, unknown frame flags rejected, strict ScreenInfo/config validation
• Reconnect: bounded connection attempts (a revived Wi-Fi link is caught in seconds, not minutes); accept-loop handshakes no longer block other clients
• GUI: idle CPU cut (config cache, tray cadence) — Task Manager shows the webview's helper processes next to kvmshare-gui; the tray icon is drawn by the GUI process, while KVM sessions survive a GUI restart
• Client injectors now log dropped unmapped keys (throttled) — 'some keys do nothing' is no longer silent
• Trust model documented honestly in docs/04-wire-protocol.md §4.7
