Feature: trash-all / bulk trash by query (e.g. gog gmail trash-all "from:x")

[stephenandrew16]

Problem

When deleting large volumes of emails from a sender, the current workflow requires:

1. gog gmail msgs list "from:x" --all to collect IDs
2. A loop of gog gmail trash <id> calls — one per message

With 400+ emails, this triggers Gmail API rate limits (403 rateLimitExceeded), requiring throttling to ~1 req/sec and taking 7+ minutes.

Workaround Discovered

gog gmail batch modify --add TRASH --remove INBOX <ids...> works and handles hundreds of IDs in a single API call. But it requires a two-step list-then-batch pipeline.

Feature Request

Add a trash-all (or trash --query) command that combines search + batch modify in one step:

gog gmail trash-all "from:thrivemarket.com" --account user@gmail.com
# or
gog gmail trash --query "from:thrivemarket.com" --all --account user@gmail.com

This would internally:

1. Paginate through all matching message IDs
2. Batch-modify them (add TRASH, remove INBOX) in chunks of 100–1000

Why not batch delete?

gog gmail batch delete requires the https://mail.google.com/ scope which many users won't have granted. Batch modify with the TRASH label works with the standard gmail.modify scope.

Impact

Makes bulk inbox cleanup (unsubscribe + delete workflows) fast and ergonomic instead of requiring scripted workarounds.
