Pull request overview
Adds a Go (preview) runtime reference to the azure-cloud-migrate Azure Functions migration documentation set, and updates shared migration rules/mapping docs so they correctly account for Go’s preview status and triggers-only programming model.
Changes:
- Introduces a new Go runtime reference (
runtimes/go.md) documenting setup, supported triggers, SDK-based I/O patterns, retry semantics, and Flex Consumption constraints. - Expands Lambda → Functions programming-model mapping and runtime-specific links to include the Go worker (preview).
- Updates shared rules to require explicit user confirmation for preview runtimes and to document Go’s “SDK for all non-HTTP I/O” exception.

Rick Winter (@RickWinter) - apologies on the delayed turn around on this. I was waiting for some go quick start templates to be live before resuming work on this PR. I've addressed all your feedback on this. Could you please take another look? |

The existing runtime triggers are included in one file rather than different files - https://github.com/microsoft/GitHub-Copilot-for-Azure/blob/main/plugins/azure-skills/skills/azure-cloud-migrate/references/services/functions/runtimes/java.md was there a challenge with token or length of the file when you try the same? |

Summary
Adds a Go (preview) runtime reference for the Azure Functions Lambda-migration skill, based on the
azure-functions-golang-workerSDK.What's in
runtimes/go.mdfunc init --worker-runtime goscaffolding (host.json,local.settings.json), scoped as local-only per Microsoft Learn.DefaultAzureCredentialfor non-HTTP I/O (Go worker is triggers-only by design).sdk.RecoverTo/sdk.Recover).appbinary, zip permission bits, EventGrid-source blob-trigger requirements).Supporting edits
Small carve-outs in
code-migration.md,global-rules.md, andlambda-to-functions.mdso the shared migration rules ("nofunction.json", "bindings over SDKs", programming-model mapping) know about Go and preview-runtime confirmation.
