Compose a performance report now

Composes a report from Adako's synced data and stores it, so it also has a permanent web page. Returns immediately — no platform calls, no waiting. Free. Use when: the user asks how a period went, wants a summary to forward, or asks for "a report" or "a brief" — including when they name one platform, because this covers every connected account and keeps the page. Prefer it over the per-platform performance tools whenever the answer is meant to be kept or sent on: those read one platform live and store nothing. Do not use when: the user asks about today — today is still syncing; use the live performance tools for "right now". report_type: performance_brief (totals, per account, top campaigns), detailed_analysis (adds the biggest movers), executive_summary (totals and a few lines). Pass either date_range or start_date + end_date, never both. Every period is compared with the equally long period immediately before it. Periods follow each account's own timezone and cover complete days only: a day that has not ended in an account's timezone is left out, and the report says when an account's days differ from the headline period. Returns the report as markdown plus a link to its page. The user can email it to themselves from that page; for recurring delivery use schedule_brief. If you are unsure which accounts, cadence or period the user means, ask rather than guessing.
