Quiet cloud terminal creation tabs

[lawrencecchen]

Cloud terminals opened with Cmd+D or Cmd+T now use the initial label terminal and keep the tab strip free of the creation spinner. The existing pane-level failure and retry behavior remains unchanged.

Summary by cubic

Previously, cloud terminals opened with Cmd+D or Cmd+T showed their display title and a tab-strip spinner while being created. They now open with the label terminal and keep the tab strip quiet; failure and retry still surface in the pane itself.

^{Written for commit 89a7a14. Summary will update on new commits.}

📝 Walkthrough

Walkthrough

Cloud manual-mirror tabs now use the localized title "terminal" and never show loading indicators. Cloud-terminal reservation failure and retry handling no longer changes tab loading state.

Changes

Cloud terminal tab behavior

Layer / File(s)	Summary
Manual-mirror tab creation and loading state Sources/Surfaces/Workspace+CloudManualMirror.swift	Cloud manual-mirror tabs use a shared localized title, start without loading indicators, and ignore loading-state updates.
Quiet reservation failure and retry Sources/Surfaces/Workspace+CloudTerminalReservation.swift	Reservation failure and retry handling no longer drives the tab-strip spinner. Comments describe pane-level status and quiet tab behavior.

Explanation

The PR introduces the user-facing tab title terminal through String(localized: "panel.cloudTerminal.title", defaultValue: "terminal"), so it uses the required localization API. However, the authoritative head has no panel.cloudTerminal.title entry in Resources/Localizable.xcstrings, and the PR changes no catalog file. This violates the rule requiring a matching catalog entry with translations for every supported locale. The affected catalog currently contains 20 locale codes: ar, bs, da, de, en, es, fr, it, ja, km, ko, nb, pl, pt-BR, ru, th, tr, uk, zh-Hans, and zh-Hant.
