Introduces session-scoped Remote Control via --remote-control and /remote-control, lifts the default 5-minute timeout on headless runs, adds structured AGY_ERROR output on stderr, improves word-wise navigation in the prompt editor, and fixes Remote Control workspace permission inheritance, oversized file edit storage limits, full-screen artifact text selection, queued /model switching, and /rewind snapshot resolution.

Added Remote Control (start a connection via --remote-control startup flag or /remote-control slash command) to create a session-scoped remote connection for following and controlling your active terminal session from another device. Typing /remote-control off or closing the session automatically tears down the tunnel and unregisters the device from the active Remote Control session list.
Changed the default timeout for headless (-p / --prompt) runs from 5 minutes to unlimited so long-running agent turns run until the response completes unless --print-timeout is passed explicitly, and enabled daemon background commands in headless GEMINI_API_KEY sessions so background servers stay running after the turn finishes.
Improved headless (-p / --prompt) error reporting when a turn terminates on an agent or model API failure: the CLI now prints a structured AGY_ERROR: {...} JSON line on stderr with canonical status, HTTP or gRPC error code, retryability, and error ID (including HTTP status mapping for GEMINI_API_KEY SDK errors) and exits with code 3 instead of 1.
Improved word-wise cursor movement (Alt+F, Alt+B, and Ctrl/Alt+Arrow keys) and word deletion (Ctrl+W, Alt+Backspace, and Alt+D) in the prompt editor to stop at punctuation boundaries instead of only whitespace, making it easy to step through or delete individual segments of file paths, URLs, and flags.
Fixed turns triggered from a connected Remote Control session or running across secondary workspaces executing without the CLI session's active permission mode, cycle mode, and non-workspace file access grants.
Fixed artifacts in the Remote Control companion rendering as plain .md file links instead of rich artifact cards when the CLI's application data directory differs from the default bundle name.
Fixed text selection in the full-screen artifact viewer capturing the line-number gutter and trailing padding; dragging across the viewer now highlights and copies only the document text, with Ctrl+C to re-copy an active selection, Esc to clear it, and Shift+drag for native terminal selection.
Fixed submitting /model while a turn is already running switching the active model immediately in the middle of the in-flight turn; the one-shot model switch now waits until the queued prompt begins executing so the running turn and any earlier queued prompts finish on the session's original model.
Fixed file edits with diffs larger than 1 MiB exceeding the conversation storage limit and force-clearing the session; oversized edits now preserve their line-change statistics while omitting the raw diff body from stored conversation history and skipping the elided diff during /rewind reverts.
Fixed /rewind conversation reverts and forks sweeping backward to an older workspace snapshot when recent snapshot commits were skipped, which could silently overwrite kept work; snapshot lookup now sweeps forward from the target step and falls back to step-by-step revert replay when no later snapshot exists.
