[Bug] Plugin marketplace installation fails silently across projects

[serivas]

Bug Description Bug: Plugin installation from marketplace fails silently in other projects

Steps to reproduce:

1. Install a plugin (e.g., bash-lsp@andes) in Project A via /plugin → marketplace
2. Go to a different Project B
3. Try to install the same plugin via /plugin → marketplace → andes → bash-lsp
4. Installation appears to do nothing — plugin doesn't appear as installed

Expected: Plugin installs (either at user or project level)

Actual: Nothing happens, no error message, plugin not added to settings

Workaround: Manually add "bash-lsp@andes": true to ~/.claude/settings.json

Notes:

• The plugin was previously installed at project-level (.claude/settings.json) in Project A
• It was NOT in user-level settings (~/.claude/settings.json)
• The marketplace UI gave no indication of failure

Environment Info

• Platform: linux
• Terminal: vscode
• Version: 2.0.76
• Feedback ID: 21dfae46-caeb-46d6-9bd1-f4724730319f
