Prepare mcp_dart_cli 0.1.9 release

[leehack]

Summary

• Bump mcp_dart_cli to 0.1.9 and mark the changelog release.
• Suppress update checks for mcp_dart serve because stdout is MCP protocol traffic.
• Run the core workflow for CLI changes too, so Codecov project coverage has both root and CLI coverage uploads.

Validation

• dart format .
• dart analyze
• PYTHON=/opt/UnitySrc/personal/mcp/mcp_dart-cli-release-prep/.dart_tool/python-interop/bin/python dart test
• dart run bin/mcp_dart.dart conformance --suite all --json
• sh -n tool/install.sh
• dart pub global run pana --no-warning --exit-code-threshold 0 (160/160)
• CI-layout dart pub publish --dry-run for nested CLI package (0 warnings, 1 expected dependency override hint)
• git diff --check

PowerShell installer syntax was not checked locally because pwsh is not installed on this machine; the CLI workflow covers it.
