Add Xcode Cloud build log viewing via artifacts

[Codex]

Xcode Cloud builds lacked an in-extension way to view running/completed build logs akin to CI UIs.

• Log artifacts retrieval: Added artifact download support to the App Store Connect client and filtering for log/text artifacts.
• View logs command/UI: Implemented xcodecloud.viewBuildLogs command with quick-picks for build run/action selection; outputs fetched logs to an “Xcode Cloud Logs” channel; exposed from build run/action context menus.
• Safety/telemetry: Guarded against null clients and empty selections; minimal lint-level additions.
• Tests: Added unit coverage for log artifact filtering.

// Fetch and display logs for a build action
const artifacts = await client.getBuildActionArtifacts(actionId);
const log = await client.downloadArtifactContent(filterLogArtifacts(artifacts.data)[0].id);
logChannel.append(log.content);

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• update.code.visualstudio.com
  • Triggering command: /home/REDACTED/work/_temp/ghcca-node/node/bin/node node /home/REDACTED/work/vscode-xcode-cloud-control/vscode-xcode-cloud-control/node_modules/.bin/vscode-test (dns block)
  • Triggering command: /home/REDACTED/work/_temp/ghcca-node/node/bin/node node /home/REDACTED/work/vscode-xcode-cloud-control/vscode-xcode-cloud-control/node_modules/.bin/vscode-test ACCEPT tr [:up�� control node ode control lint ndor/bin/getconfnpm run check-types && npm run lint && node esbuild.js lsb_release loud�� k/vscode-xcode-cloud-control/vscsrc/lib/appstoreconnect/client.ts sh ndor/bin/git control dirname /opt/hostedtoolceslint src git (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
