PR Summary

Medium Risk
Changes copilot integration input schemas and required-field validation for API-key params on hosted deployments; behavior is scoped to schema generation with explicit edge cases for conditional hosting.

Overview
Fixes hosted-key integration tools in copilot by aligning gateway tool schemas with server-side key injection so call-integration-tool no longer demands an API key the model cannot supply.

createUserToolSchema gains hostedKeySupport. On hosted deployments, copilot integration schemas are built with hostedKeySupport: isHosted from buildIntegrationToolSchemas. For tools with unconditionalhosting config, the configured apiKeyParam stays visible for optional BYOK but is removed from required, with copy noting Sim’s hosted key. Conditionalhosting.enabled tools, non-hosted tools, and self-hosted builds keep the key required as before.

Tests cover hosted vs self-hosted, conditional hosting, plain tools, and payload wiring.
