chore(mcp-gateway): use kilosessions gateway hostname

[pandemicsyn]

Summary

• Update the MCP gateway production hostname from mcp.kilo.ai to mcp.kilosessions.ai.
• Update the Worker route, production gateway base URL, app fallback gateway URL, generated Worker bindings, and related test fixtures so canonical MCP resource URLs use the new hostname consistently.
• Keep the app OAuth origin on app.kilo.ai; only the protected-resource/runtime hostname changes.

Verification

• No manual verification performed; this change only updates configuration and test fixtures, and validation was limited to automated checks.
• Additional manual verification details:

N/A

Reviewer Notes

• This is a production hostname migration only; there are no existing configs
• The Worker route now targets the kilosessions.ai zone, so DNS/TLS setup for mcp.kilosessions.ai must exist before deployment.

Executive Summary

Incremental review of one additional commit (fix(mcp-gateway): use custom domain route): switches wrangler.jsonc Worker routing from a zone-route pattern (mcp.kilosessions.ai/* + zone_name) to a Cloudflare custom domain entry (custom_domain: true). The change is correct and no new issues found across all reviewed files.
