Suspend-and-handoff passthrough from the Ink TUI to a cli-agent PTY session:
mint an attach ticket, open the cli-session WebSocket, enter the alternate
screen + raw mode, stream WS scrollback/data frames to stdout, frame stdin
bytes into input messages, propagate resizes, and ACK consumed bytes for flow
control. Detach chord Ctrl-] restores the terminal and remounts Ink; a dropped
WS surfaces the error and restores the terminal cleanly.
Untrusted terminal output is neutralized through the same hardening filter the
dashboard WS bridge uses (re-exported from @fusion/dashboard) so OSC 52, non-
http(s) OSC 8 links, and device-status queries are stripped before reaching the
host TTY — the riskiest leg, since the host terminal honors more sequences than
xterm.js. CJK/double-width bytes pass through verbatim.
- packages/cli/src/commands/dashboard-tui/terminal-attach.ts (passthrough loop +
injectable WS transport for tests)
- controller.openTerminalAttach() Ink integration (unmount/run/remount)
- adds `ws` runtime dep to packages/cli
- re-exports neutralizeTerminalOutput/flushTerminalOutput from @fusion/dashboard
