🟡 Changes recommended

Approval is blocked by unresolved critical lifecycle and DOM-proxy issues that can prevent editor activation and leak per-tab editor instances, plus inconsistent loaded-state handling after asynchronous errors.

What changed in this PR

Updates CellDL Editor to 0.20261105.0, replacing the shared editor with independent instances so each CellDL file tab preserves its own editor state.

Changes:

• Embed one CellDL Editor instance per file view.
• Add keyboard-client coordination and a persistent idle editor.
• Remove the obsolete shared editor host and state management.
• Update CSS scoping, dependencies, versions, changelog, and lockfiles.

🟡 Changes recommended

Two active correctness issues remain: a released client can be reassigned by a queued open operation, and editor-state failures leave the client marked loaded with enabled exports and continued edit events.

🔵 Needs a closer look

The pooled editor’s asynchronous lifecycle, Teleport reuse, and cross-instance keyboard coordination require manual multi-tab and failure-path runtime validation beyond static review.
