CLI setup command, Search API aggregation, and Console fixes#

Search API requests can set aggregate: true to combine related memory fragments into synthesized results, the CLI gets a guided setup command and interactive init, and several CLI fixes cover --no-browser, upload tags, and scoped keys.

Improvements

Set aggregate: true in Search API requests to combine related memory fragments into synthesized results.
Run supermemory setup for guided agent setup; supermemory init is now interactive and invalid commands return readable errors.

Fixes

The CLI now honors --no-browser, preserves upload tags, formats document lists correctly, and marks scoped API keys.
Console now explains when a plugin requires a paid plan instead of silently redirecting to Billing.
