fix(desktop): switching back to the stable update channel no longer errors

[elkaix]

Problem

On the Updates settings page, choosing Stable after Beta or Nightly shows Channel must be a string, but got: null. configureExplicitConsent assigned null to autoUpdater.channel; electron-updater's setter rejects non-strings once a channel has been set.

What changed

• apps/desktop/src/updater.ts: stable now sets electron-updater's default channel name latest explicitly (same latest-mac.yml, no behavior change for fresh installs).
• apps/desktop/tests/updater.spec.ts: the electron-updater mock enforces the real channel setter rules, so the existing channel-switch test fails on the old code (verified) and asserts latest now.

[skip changeset] — desktop app, not a changesets-managed package.

Summary by CodeRabbit

• Bug Fixes
  • Improved stable-channel update handling by explicitly selecting the latest stable release.
  • Prevented update configuration from being left in an invalid or inconsistent channel state.

📝 Walkthrough

Walkthrough

The updater now explicitly selects the latest channel for stable updates. The test mock validates channel assignments and tracks state through a backing field. The strict-consent test expects latest.

Changes

Stable updater channel

Layer / File(s)	Summary
Channel selection and validation apps/desktop/src/updater.ts, apps/desktop/tests/updater.spec.ts	The updater uses STABLE_UPDATER_CHANNEL with the value latest for stable updates. Beta and nightly channels remain unchanged. The test mock validates assignments, cleanup resets its backing state, and the strict-consent test expects latest.

Estimated code review effort: 1 (Trivial) | ~5 minutes

Merge Risk: 🟡 Moderate · up to d70ab

The updater channel fix is localized, but the modified test currently fails lint because of a loose null comparison. Clean up that lint issue before merging.
