Update Claude Code to 2.0.22 and Copilot CLI to 0.0.344, add --disable-builtin-mcps flag

[Copilot]

Summary

This PR updates the agentic CLI tools to their latest stable releases and adds support for the new --disable-builtin-mcps flag introduced in Copilot CLI 0.0.344.

Changes

CLI Version Updates

• Claude Code: 2.0.21 → 2.0.22
• GitHub Copilot CLI: 0.0.343 → 0.0.344

Both are minor patch releases with no breaking changes identified.

New Feature: --disable-builtin-mcps Flag

Added the --disable-builtin-mcps flag to the Copilot engine configuration. This flag was introduced in Copilot CLI 0.0.344 to disable built-in MCP servers (currently the GitHub MCP server).

Why this flag is needed:

The flag ensures that gh-aw has full control over MCP server configuration. When the flag is present:

• Built-in MCP servers are disabled
• Only explicitly configured MCP servers (via mcp-config.json) are active
• This prevents conflicts between gh-aw's MCP configuration and Copilot CLI's built-in servers

Implementation details:

The flag is added early in the command line arguments (after basic flags like --add-dir and --log-level, but before tool-specific flags):

copilot --add-dir /tmp/gh-aw/ \
        --log-level all \
        --log-dir /tmp/gh-aw/.copilot/logs/ \
        --disable-builtin-mcps \
        --allow-tool 'github(...)' \
        ...

Testing

• Added test case to verify the flag appears in generated execution steps
• All existing unit and integration tests pass
• Recompiled all 64 workflows successfully with the new versions

Files Modified

• pkg/constants/constants.go - Updated version constants
• pkg/workflow/copilot_engine.go - Added --disable-builtin-mcps flag
• pkg/workflow/copilot_engine_test.go - Added test coverage
• .github/workflows/*.lock.yml - Recompiled with new versions (30 files)
