fix(mitm): update Kiro API endpoint to runtime.us-east-1.kiro.dev

Kiro IDE changed its API endpoint from q.us-east-1.amazonaws.com to
runtime.us-east-1.kiro.dev. Old domains kept as fallback.

- mitm/config.js: add new hosts to TARGET_HOSTS + getToolForHost()
- cliTools.js: update mitmDomain to new endpoint
- mitmToolHosts.js: prepend new domain (keep legacy for compat)
- dataDir.js: on Windows ignore Unix-style DATA_DIR paths
