Commits reviewed (range v4.160.1...v4.160.2)

• 6ebea4d — [chore]: bump homebrew cask to 4.160.1 — skipped: bot version-bump commit, no user-facing change.
• 6fcec06 (chore(link): remove the desktop link feature #5570) — chore(link): remove the desktop link feature — docs update warranted: this removes the entire "Desktop Link" feature — the deco link CLI command, the Link Daemon, the desktop sandbox provider (user-desktop), the Desktop Loop, and all supporting NATS/tunnel infrastructure. This was a documented, user-facing capability (running an agent locally via a linked desktop machine) and its removal makes several doc sections inaccurate.
• 9857286 — [release]: bump changed workspace versions — skipped: bot version-bump commit, no user-facing change.

Doc files changed

• en/studio/agents.mdx / pt-br/studio/agents.mdx — Removed the "Local" runtime group (Decopilot-on-desktop, Claude Code, Codex via deco link) from "Where an agent runs." The runtime picker now only documents the single Decopilot (cloud sandbox) option. Removed the "Windows" section, which only existed to document Link Daemon behavior on Windows.
• en/studio/architecture.mdx / pt-br/studio/architecture.mdx — Reworked from three tiers (Edge / Cloud cluster / Desktop) down to two (Edge / Cloud cluster). Removed the Desktop column from the architecture diagram, the NATS "pull work-queue to desktop" responsibility, the "Pull" run transport, the "Cloud vs. desktop sandboxes" comparison table, the desktop half of the org-fs mount table, and the entire "## Desktop" section describing the Link Daemon. The "At a glance" summary no longer mentions desktop sandboxes.
• en/studio/decopilot/overview.mdx / pt-br/studio/decopilot/overview.mdx — Removed the "macOS desktop links" callout about network-volume permissions for deco link sandboxes, since sandboxes now only run in the cloud.

pt-br versions were translated to match (prose and headings translated; code, URLs, and product terms like "agent", "sandbox", "MCP" kept in English, per doc convention).

Consistency notes

• The ArchitectureDiagram.astro component (apps/docs/client/src/components/ArchitectureDiagram.astro) likely still renders a visual desktop/link column and may need a matching update. It's outside apps/docs/client/src/content/deco-studio/ so it was not touched by this automated PR — flagging for a human follow-up.
• Checked quickstart.mdx, concepts.mdx, overview.mdx, connections.mdx, self-hosting/quickstart.mdx, self-hosting/deploy/*.mdx, decopilot/tools.mdx, and all other .mdx files under en/ for "link"/"desktop"/"tunnel" references — no other stale mentions found. Note: "linked GitHub repo" phrasing in agents.mdx and decopilot/tools.mdx/overview.mdx refers to a distinct, still-valid feature (an agent's sandbox linked to a GitHub repo) and was intentionally left unchanged.
• No other doc files needed edits for this release.

  • Removed Windows daemon prerequisites and macOS desktop link callouts.
  • Mirrored all edits in pt-br pages.

• Migration

  • Agents now always run in the managed cloud sandbox; deco link is no longer supported.
