[main] Cherry-pick MSRC fixes (#320659) * OTel visibility in Copilot Chat UI (#47) * [msrc/1.123] 114763 * Add maxAttributeSizeChars configuration to OpenTelemetry settings --------- Co-authored-by: Zhichao Li <zhichli@microsoft.com> (cherry picked from commit 042dc59dbb51f58ef03a6909d5dfb0292a6b2576) (cherry picked from commit be6ab8b589a75e6b64a95dc73763e5d23a20bb1a) * Prompt before connecting to non-loopback remote host:port authorities (#46) A direct `<host>:<port>` remote authority (no resolver `+` prefix) bypasses resolver extensions and connects straight to the given server. Since this form can originate from untrusted sources (e.g. the `remoteAuthority` of a `.code-workspace` file), a crafted workspace could silently point the window's extension host backend at an attacker-controlled server. Centralize a confirmation prompt at the connection point in the renderer: when resolving a direct authority whose host is not loopback (localhost, 127.0.0.1, ::1), ask the user to confirm before connecting and abort if declined. Add `isLoopbackHost` helper and tests.
