Copilot CLI v1.0.4: Shell Streaming & MCP Auth

Copilot CLI 1.0.4 adds shell streaming RPC methods, fixes MCP OAuth with Entra ID, introduces adaptive colors, and replaces /pr open with /pr view.

TL;DR

New RPC methods for streaming shell command execution with stdout/stderr
MCP OAuth re-authentication now handles Microsoft Entra ID and port changes reliably
Adaptive color engine with graceful degradation on limited-color terminals
Breaking: /pr open replaced with /pr view [local|web]

session.shell.exec and session.shell.kill RPC methods — Execute shell commands with streaming stdout/stderr output for better agent integration
Adaptive color engine — Dynamic color modes with interactive theme picker, gracefully degrades on limited-color terminals and Windows
OpenTelemetry instrumentation — Observability into agent sessions, LLM calls, and tool executions
CommonJS extension support — Extensions can now be written as extension.cjs modules
--reasoning-effort CLI flag — Set reasoning effort level per invocation
configure-copilot sub-agent — Manage MCP servers, custom agents, and skills via the task tool
Hook confirmation requests — Hooks can request user confirmation before tool execution with 'ask' permission decision
Path permission one-time approval — Dialog now offers one-time approval option in addition to allowlist
Instruction file picker improvements — Show individual file names with [external] labels for injected files
disableAllHooks flag — Disable all hooks from configuration file
Azure DevOps repository identification — Support in session logs
Session export header formatting — Each field renders on its own line in shared gists
Extensions count in startup message — Environment loaded message now shows loaded extensions count

MCP OAuth re-authentication — Now works reliably when callback port changes or using Microsoft Entra ID with proper resource indicators and refresh token support
Custom agents in ACP mode — Plugins from --plugin-dir now load correctly
Autopilot mode error handling — Stops continuing after API errors instead of looping indefinitely
Status line context window percentage — No longer inflates across turns by using last call's tokens instead of cumulative totals
Kitty keyboard protocol — Properly disabled on suspend when using alternate screen
Reasoning headers display — Only show when it's the only reasoning text available
Terminal reset on crash — CLI crash no longer corrupts shell state
Auto-update SAML errors — Retries without authentication token on SAML enforcement errors
Interactive shell initialization timeout — No longer times out on slow machines
Windows shell performance — Faster shell commands by skipping PowerShell profile loading
