EmuLabZip 0.6.0

Phase 6: network power tools, layout and accessibility, sessions, comparing devices.

Added

• Mocks and breakpoints: rules that answer a request yourself (status, headers, text or binary body, delay), slow it
  down, block it, or hold the request and/or the response so you can edit it and continue. A Rules dialog with presets
  and "Mock this response" from any request, a drawer for held messages, emulabzip net --rules file.json. Held
  messages continue by themselves after two minutes.
• WebSocket messages: a frame parser (RFC 6455, fragments, control frames, permessage-deflate) feeds a Messages
  tab with direction, text, JSON and hex, and goes into the HAR export as _webSocketMessages.
• Packet capture import: .pcap and .pcapng files (such as emulator -tcpdump writes) become requests, TLS
  connections named by their server name, and DNS lookups, with TCP streams put back together. In the app (Import)
  and as emulabzip net import.
• HTTP/3 to servers: with Use HTTP/3 to servers on, hosts that announce Alt-Svc: h3 are reached over QUIC,
  with a fallback to TCP. A Proto column shows h1, h2 or h3. Hide HTTP/3 from apps (on by default) keeps apps
  from trying QUIC around the proxy.
• Layout and accessibility: the views on screen with their names, sizes and flags (uiautomator on Android, the
  Accessibility API on the iOS Simulator), a Layout view with the screenshot, the tree and properties, and an audit of
  missing labels, touch targets, contrast and duplicate names. emulabzip layout and emulabzip a11y --fail-on, and the
  MCP tools get_layout and audit_accessibility.
• Sessions: a recorder that writes logs, samples, requests, crashes and screenshots into one .ezsession file
  (still readable if the run was killed), a Sessions view, emulabzip session record and session show, and the MCP
  tools list_sessions and session_summary.
• CI mode: emulabzip ci -o run.ezsession -- <command> records around a command, keeps its exit code, writes a
  Markdown report (also to $GITHUB_STEP_SUMMARY), and --fail-on-crash fails a run whose app crashed.
• Compare: two devices side by side with both screens, CPU and memory charts, and a table of what differs;
  emulabzip compare.
• Live tests for all of it in tools/live-tests.sh, and a capture written by a real emulator as a test fixture.

Changed

• WebSocket connections are no longer opaque tunnels: the bytes still pass unchanged, and the messages are read from
  them.
