Add icons to MCP server tools

[Copilot]

MCP v1.2.0 adds icon support for tools. Added visual icons to all 7 registered MCP tools for better discoverability in MCP-aware UIs.

Changes

• Icon assignments: Added emoji icons to each tool registration matching their functionality:

  • 📊 status - workflow overview
  • 🔨 compile - build/validate
  • 📜 logs - execution logs
  • 🔍 audit - investigation
  • 🔎 mcp-inspect - introspection
  • ➕ add - import workflows
  • 🔄 update - sync workflows

• Test coverage: Added TestMCPServer_ToolIcons to verify all tools expose icons correctly

Implementation

mcp.AddTool(server, &mcp.Tool{
    Name: "status",
    Description: `Show status of agentic workflow files...`,
    Icons: []mcp.Icon{
        {Source: "📊"},
    },
}, handler)

Icons appear in MCP Inspector, Claude Desktop, and other MCP v1.2.0+ clients.

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:

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)

<issue_title>[plan] Add tool icons to MCP server tools</issue_title>
<issue_description>## Objective

Add visual icons to the 7 registered MCP tools using the new v1.2.0 icon support (SEP-973) for better tool discoverability in MCP-aware UIs.

Context

v1.2.0 adds icon support for tools via the Icon field. This improves UX by providing visual cues for each tool's purpose.

Approach

Update tool registrations in pkg/cli/mcp_server.go to include icons:

Recommended Icons:

• 📊 status - Workflow status overview
• 🔨 compile - Build and validate workflows
• 📜 logs - Workflow execution logs
• 🔍 audit - Deep dive investigation
• 🔎 mcp-inspect - Server introspection
• ➕ add - Import workflows
• 🔄 update - Sync workflows

1. Add Icon field to each mcp.AddTool() call
2. Use emoji or icon URLs as appropriate
3. Test icons display correctly in MCP inspector

Files to Modify

• pkg/cli/mcp_server.go - Add Icon field to tool definitions

Acceptance Criteria

• All 7 tools have appropriate icons
• Icons display correctly in ./gh-aw mcp inspect --inspector
• Icons are visible in MCP-aware clients
• Code follows v1.2.0 icon API patterns
