Add Kiro setup instructions to README

[ybenouag]

Description

Kiro (https://kiro.dev) supports MCP servers via ~/.kiro/settings/mcp.json (user-level) or /.kiro/settings/mcp.json (project-level). The Setup section of the README should include a Kiro subsection alongside Claude Code, Claude Desktop, and GitHub Copilot.

Suggested config snippet:

{
"mcpServers": {
"matlab": {
"command": "/fullpath/to/matlab-mcp-core-server",
"args": ["--matlab-root", "/path/to/MATLAB/R2025b",
"--matlab-display-mode", "desktop"],
"disabled": false,
"autoApprove": []
}
}
}

Notes to cover:

• Replace the command path with the absolute path to the binary.
• --matlab-root can be omitted if MATLAB is on PATH.
• Kiro auto-reconnects on config changes; the command palette ("MCP") also exposes reconnect options.
