Agent Host Copilot CLI: Support async shell completion notifications (#318511) * Support Copilot async shell completions with AHP message origins * removed unused import * fix test

Stream built-in shell output over AHP terminal channel (#327067) * Stream output for SDK built-in shell tool * better todo comment * Bump Copilot SDK to 1.0.8 preview Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> Copilot-Session: 5083fb1f-34d7-44bf-82a1-c4582e57683b * Exclude unused Koffi native modules Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> Copilot-Session: 5083fb1f-34d7-44bf-82a1-c4582e57683b * Adopt AHP terminal completion changes and stream built-in shell output over the terminal channel - Re-vendor agent-host-protocol: terminalComplete removed, exitCode/preview/truncated fold into terminal.result (TerminalCommandResult), isPty added to ToolResultTerminalContent and TerminalState - shell_exit now lands on the tool call's terminal block; history replay synthesizes a non-pty block keyed by toolCallId - Stream tool.execution_partial_result into an output-only agenthost-terminal channel (isPty false) instead of replacing Text content - Normalize LF to CRLF in AgentHostPty when the channel is plain text - Re-apply local CompletionItem.label extension clobbered by the protocol sync (still needs upstreaming) * Track last emitted snapshot for non-pty shell streaming The runtime emits cumulative plain-text snapshots (ANSI-stripped, throttled) that are capped to the leading ~10KB with a growing truncation marker, so a length-based delta goes stale once output exceeds the cap. Track the last emitted snapshot and prefix-check it: extend in place while the snapshot grows, reset the channel and rewrite when it was rewritten. * Normalize output terminal data to CRLF in the terminal manager Pty-backed channels already carry CRLF because the pty converts output line endings; do the same for output-only channels at the point data enters the channel, so terminal frontends render both identically and AgentHostPty needs no isPty-specific handling. Reverts the client-side normalization. * no need to complicate too much with lf crlf * Fix output-only shell command lifecycle rendering * keep non pty output handling scoped to agent hsot * fix output only terminal completion state * simplify agent host output terminal lifecycle * leave unnncessary background stuff out * scope non pty shell terminals by session * change ahp version to be proper * agentHost: regenerate AHP completion types --------- Copilot-Session: 5083fb1f-34d7-44bf-82a1-c4582e57683b

Dynamically resize and reflow inline chat terminal output (#328313) * Resize chat terminal output mirror to available content width Reflow detached terminal command/snapshot mirrors when the expanded output container width is known, and cover the column math with unit tests. * Fix mirror layout line count and window DPR after content-width resize Use the mirror terminal window DPR and rendered row count after resize so box height and column math stay correct across windows and reflow. * Prefer rendered row count and measured padding for mirror layout Only trust a persisted snapshot lineCount for truncated output, and measure the mirror's horizontal chrome from computed styles like the panel terminal does, keeping the 24px estimate as a pre-attach fallback. * Keep truncated snapshot height stable and measure the terminal gutter Snapshot layout now applies the same truncated lineCount rule as render so an explicit count survives resizes, the pre-attach chrome estimate matches the 20px workbench xterm gutter, resize errors are routed to onUnexpectedError, and the live mirror re-checks cols after waiting for an in-flight flush. * Fire and forget the resize relayout like other terminal code

Block auto-approve for sed scripts that run commands or write files (#329216) * Tighten sed argument handling in terminal auto-approve defaults The sed deny rules only matched flag-based forms (-e/-f/--expression/--file) and s/// flags, so positional script arguments fell through to the allow rule. Extend the deny patterns to cover standalone script commands and mirror the change in the agent host fallback defaults.
