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 unconditional hosting config, the configured apiKeyParam stays visible for optional BYOK but is removed from required, with copy noting Sim’s hosted key. Conditional hosting.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.
