Greptile Summary

This PR revises desktop release streams and update handling, fixes Copilot abort ordering, and adjusts Mothership interaction rendering. It also removes desktop folder-management controls while persistent filesystem grants remain active.

• Renames prerelease streams from alpha/beta to dev/staging while preserving legacy compatibility.
• Adds origin-aware desktop update feeds, stricter manifest validation, timeouts, and one-action download/install behavior.
• Writes Copilot’s explicit abort marker before terminating the local stream.
• Collapses superseded credential prompts and streamlines single-select question interaction.
• Removes the Desktop settings interface for local-folder grants.

Confidence Score: 3/5

The PR should not merge until users retain an in-app way to inspect and revoke persistent local-folder access.

Existing filesystem grants survive restarts and remain available to Copilot tools, while this change removes the sole settings UI that listed and revoked them; the new route test also violates the repository’s absolute-import convention.

Files Needing Attention: apps/sim/app/workspace/[workspaceId]/settings/components/desktop/desktop.tsx; apps/sim/app/api/desktop/update/latest-mac.yml/route.test.ts

Security Review

The Desktop settings change removes the only in-app revocation path for persistent local-folder grants. Existing grants are restored at startup and remain usable by Copilot filesystem tools, leaving users unable to inspect or revoke that access from the application.

Important Files Changed

Filename	Overview
apps/desktop/src/main/updater.ts	Reworks update-channel resolution, feed probing, candidate validation, timeouts, and explicit download-to-install behavior; no confirmed blocking updater defect remains.
apps/sim/app/api/desktop/update/latest-mac.yml/route.ts	Selects update streams from the request hostname, distinguishes authoritative no-release responses, and validates manifest versions against release tags.
apps/sim/app/api/copilot/chat/abort/route.ts	Moves the bounded Go abort-marker request before local SSE teardown to prevent deliberate stops from being misclassified.
apps/sim/app/workspace/[workspaceId]/settings/components/desktop/desktop.tsx	Simplifies desktop settings but removes the only UI for inspecting and revoking persistent local filesystem grants.
apps/sim/app/api/desktop/update/latest-mac.yml/route.test.ts	Adds update-feed coverage but introduces a relative import contrary to the apps/sim absolute-import rule.
apps/sim/app/workspace/[workspaceId]/home/components/mothership-chat/mothership-chat.tsx	Marks superseded credential interactions as abandoned so historical prompts render as recaps instead of active forms.
