Runs a timeboxed 25-minute inbox batch protocol — sort by sender value, apply the 2-minute rule, batch replies as drafts, park and schedule the rest — ending with a hard count report. Use when the user says "inbox zero", "help me clear my inbox", "email sprint", "my inbox is out of control", or wants a focused email session. Don't use for ongoing daily triage rules — use email-triage — or for customer support queues — use customer-support-inbox.
