fix(workbench): add __mf__temp directory to .gitignore

[gu-stav]

Description

Module federation still generates the __mf__temp directory in the root of the bootstrapped application when running sanity init, so we need to add it to the gitignore file.

I've added it unconditionally, because if a user would enable module-federation later, it is already ignored.

---

Note

Low Risk
Small, template-only change plus a matching test assertion; no runtime logic changes beyond the generated .gitignore contents.

Overview
Bootstrapped projects from sanity init will now ignore the module federation temporary directory by adding .__mf__temp/ to the shared .gitignore template.

The federation init test is updated to assert the generated .gitignore contains this entry, and a changeset is added to ship the CLI patch release.

Changeset summary is inaccurate

.changeset/pr-1028.md line 6: The summary reads fix(workbench): add \__mf__temp` directory to .gitignore, but the actual directory name added is .__mf__temp (note the leading dot). The conventional-commit prefix (fix(workbench):`) also shouldn't appear in a changeset summary — it should be a plain user-facing sentence.

Suggested: Adds \.__mf__temp/` to the scaffolded `.gitignore` to prevent module federation temporary files from being committed.` Fix this →

Fixture gitignore is inconsistent with the template

fixtures/federated-studio/.gitignore line 31 has .__mf__temp (no trailing slash), while the new template entry is .__mf__temp/ (with trailing slash). These should match. Fix this →

[joshuaellis]

it'd be nice if we could avoid having this at the root of projects. iirc its set from the vite plugin, should we look into adding a way to change this filePath upstream do you think?

[gu-stav]

@joshuaellis Turns out it wasn't hard to add it there: module-federation/vite#670

Since it will take a while to get this merged and updated (the HMR implementation has since been done in the Vite plugin) I'm wondering if we should merge this and revert once it has landed?

Sure, i think we should be very careful about introducing the HMR behaviour in and be extra vigilant it works as intended before shipping,

[joshuaellis]

ALso need to write a follow ticket to revert this change when we do the update

[gu-stav]

@claude add an issue to the Dashboard 2.0 project, to revert the above change.

I was unable to create the issue — gh write commands (issue creation, project queries) are blocked by the tool permission settings in this environment and require explicit user approval.

To create the issue manually, you can use this pre-filled link:

Create issue →

Then add the created issue to the Dashboard 2.0 project from the issue's sidebar.

If you'd like me to retry with approved permissions, you can add gh issue create and gh project item-add to your allowed tools.
