feat(web): switch saved environments off instead of removing them

[t3dotgg]

Disconnect and Remove on a saved environment did the same thing: delete the registration, credentials, and cache. Disconnect looked temporary but was not, Remove disappeared whenever Update was shown, and there was no way to silence an errored machine without re-pairing it later.

Each saved row now has a switch as its main action. Off drops the connection, stops the retry loop, hides the error text, and pulls that machine's projects and threads out of the sidebar and load balancing. The flag is saved on the registration, so it stays off across restarts. On reconnects with no re-pairing.

Update is an icon that only shows when a connected machine is behind the client version. Remove lives in an overflow menu on every row and opens a destructive confirm. An "Update all" button appears in the section header when any connected machine has an update.

Mobile gets the same enabled flag through client-runtime. Its T3 Connect switch used to remove the environment. It now switches it off.

Before:

After:

A connected machine on an older server version. The update icon sits next to the switch, and "Update all" appears in the section header:

Closes #9685

Closes discussions

• [Feature]: ability to disable environment in the mobile app #6853

Summary by CodeRabbit

• New Features

  • Added switches to enable or disable saved environments on web and mobile.
  • Disabled environments remain saved but stay disconnected and are excluded from shared project, thread, and connection status views.
  • Added an “Update all” action and icon-style update controls for eligible environments.
  • Added long-press removal for connected environments on mobile.
  • Environment removal now uses a confirmation dialog with clearer guidance to switch environments off instead.

• Bug Fixes

  • Disabled environments no longer surface connection errors, retry states, or affect overall connection readiness.
  • Environment enabled/disabled preferences persist across sessions.

Approvability

Verdict: Not approved

Macroscope's review found this PR not approvable — This PR introduces a cross-platform saved-environment lifecycle feature that changes connection teardown/reconnection, SSH management, workspace data visibility, and load balancing. Its broad user-facing and runtime impact warrants human review despite backward-compatible storage migration and added tests.

📝 Walkthrough

Walkthrough

The change adds persisted per-environment enablement state. Disabled environments do not connect or contribute to active state aggregations. Mobile and web settings provide switches, revised removal controls, and conditional update actions.

Changes

Environment enablement

Layer / File(s)	Summary
Catalog persistence contract apps/desktop/src/app/DesktopConnectionCatalogStore.ts, apps/mobile/src/connection/storage.ts, apps/web/src/connection/storage.ts, packages/client-runtime/src/connection/*, packages/client-runtime/src/platform/*	Catalog documents store disabled environment IDs. Storage interfaces expose listing and updating enablement state. Older documents default to an empty disabled list.
Registry enablement commands packages/client-runtime/src/connection/registry.ts, packages/client-runtime/src/state/connections.ts, packages/client-runtime/src/connection/*.test.ts	The registry loads disabled environments, controls supervisor connections, preserves disabled state during re-registration, and exposes setEnabled.
Enabled environment projections apps/mobile/src/state/workspaceModel.ts, apps/web/src/state/shell.ts, packages/client-runtime/src/state/*	Workspace, shell, project, thread, and entity aggregations use enabled environments. Per-environment cached snapshots remain available.
Mobile enablement controls apps/mobile/src/features/connection/*, apps/mobile/src/features/cloud/*, apps/mobile/src/features/settings/*, apps/mobile/src/state/*	Mobile rows show switches and an “Off” state. Switch changes call setEnvironmentEnabled. Disabled rows suppress connection errors and retry state. Cloud rows support long-press removal.
Web settings controls apps/web/src/components/settings/ConnectionsSettings.tsx, apps/web/src/components/ServerUpdateAction.tsx	Web rows use switches and menus. Update actions apply only to eligible enabled environments. Removal uses confirmation dialogs, and load-balancing settings receive enabled environments only.
