[FEATURE] Plan panel auto-closes on approval, removing access to copy blocks mid-session

Problem Statement

When a plan is approved via the "Accept" button in the Claude Code VS Code extension, the plan panel closes immediately. Any copy blocks inside the plan (e.g. a v0 prompt, SQL migration, config snippet) become inaccessible the moment the user clicks accept.

The plan file is saved locally, but the user has to know the exact file path and manually open it in their editor to get back to it — which is non-obvious and breaks the workflow.

Proposed Solution

The plan panel should remain open after approval, or at minimum provide a persistent "View plan" button/link so the user can reopen it at any time during the session. The user should control when to close it, not the approval action.

Additional Context

the reason why it matters is because, plans are reference documents, not one-time reads. A user may need to copy a specific section (a prompt, a script, a config block) at any point during implementation — not just when they first approve the plan. Auto-closing the panel removes that access exactly when implementation work begins.
