Pull request overview

This PR aligns the iccDEV MCP server configuration and documentation with the maintainer request in issue #1704. It documents the GitHub Copilot coding agent MCP configuration, adds ASCII-safe "display" variants of ICC signature fields to profile_summary, resets the REST dashboard UI state when switching tools, and adds corresponding regression assertions.

Changes:

• Add a GitHub Copilot coding agent MCP configuration block to the README, mirroring the payload in issue #1704.
• Add _printable_signature and expose color_space_display/pcs_display/platform_display in profile_summary.
• Clear stale output and reset run status to Idle when a new tool is selected in the REST dashboard, with Python and UI test coverage.

File	Description
iccdev-mcp/iccdev_mcp/server.py	Adds _printable_signature helper and three *_display fields to profile_summary; the helper is passed raw integer header fields, causing a runtime TypeError.
iccdev-mcp/iccdev_mcp/rest_api.py	Resets output to Ready. and runStatus to Idle on tool selection; consistent with existing JS helpers and DOM ids.
iccdev-mcp/tests/test_server.py	Adds assertions for the new display fields and printable-ASCII invariant.
iccdev-mcp/tests/rest_dashboard_ui_test.cjs	Adds UI regression checks that tool selection clears stale output and resets status.
iccdev-mcp/README.md	Documents the Copilot coding agent repository MCP configuration.
