+Fix `configFileName` returning wrong filename for `.jsonc` config files
+
+Previously, users with a `wrangler.jsonc` config file would see error messages and hints referring to `wrangler.json` instead of `wrangler.jsonc`. This was because the `configFormat` function collapsed both `.json` and `.jsonc` files into a single `"jsonc"` value, losing the distinction between them.
+
+Now `configFormat` returns `"json"` for `.json` files and `"jsonc"` for `.jsonc` files, allowing `configFileName` to return the correct filename for each format.

+Bump the version of `@cloudflare/vitest-pool-workers` in the hello-world templates from `^0.8.19` to `^0.12.4`
+
+The version of the `@cloudflare/vitest-pool-workers` in the hello-world templates is currently `^0.8.19`, since the package is pre v1, the Caret syntax only installs the latest `0.8.x` version of the package, which is a bit outdated. So the changes here manually keep the package more up to date.
