typescript-lsp plugin: stuck in broken state — UI shows Disabled, can't enable or uninstall

Bug Report

Summary

The typescript-lsp@claude-plugins-official plugin is stuck in a broken state where:

• The plugin UI always shows Status: Disabled
• Attempting to enable it returns: Failed to enable: Plugin "typescript-lsp@claude-plugins-official" is already enabled at project scope
• Attempting to uninstall also fails silently
• After /reload-plugins, the output consistently shows 0 plugin LSP servers — the LSP never loads

Steps to Reproduce

1. Install typescript-lsp plugin via /plugin
2. Run /reload-plugins — observe 0 plugin LSP servers
3. Open /plugin menu — Status shows "Disabled"
4. Click "Enable plugin" — error: "already enabled at project scope"
5. Click "Uninstall" — no effect, plugin remains

Expected Behavior

• Plugin status should reflect actual state
• Enable/Disable/Uninstall actions should work
• After enabling, /reload-plugins should show 1 plugin LSP server

Actual Behavior

• UI state is permanently out of sync with settings.json
• settings.json correctly has "typescript-lsp@claude-plugins-official": true
• Despite this, LSP never registers and UI shows Disabled
• No actionable error shown in the Errors tab

Environment

• Platform: macOS (darwin 25.3.0)
• Shell: zsh
• Project type: Next.js / TypeScript (tsconfig.json present at project root)
• Plugin scope: project

Additional Notes

Manually editing settings.json to set the value to false had no effect — the plugin manager re-enabled it on next interaction. The plugin appears completely unmanageable once installed.
