fetch url

LIVE-fetch an authoritative DEA/MoF HTML page (e.g. a press release or web-only table) and return its text plus, when `focus` is set, a focused extraction. Authority-host gated (indiabudget.gov.in / dea.gov.in / finmin.nic.in). For a PDF use fetch_table; for a JS/interaction-gated page escalate to authority-web browser_fetch.
