CSV Guard v1.1.0

CSV Guard v1.1.0 adds destination-aware handling for formula-like CSV segments.\n\n- Choose Apostrophe prefix (default) or Excel review prefix (tab) before inspection.\n- See the underlying-data and Excel save/reopen trade-offs before downloading.\n- Excel-tab mode upgrades existing apostrophe-prefixed risky markers and stays idempotent across cell, delimiter, newline, serialization, and re-cleaning boundaries.\n- Download names and previews now expose the selected mode; tab characters appear as ⇥ in previews.\n- Static guidance links to OWASP and explicitly avoids universal or permanent safety claims.\n- Shared latest-operation coordination prevents stale file reads from overriding a newer mode.\n\nVerification: production build, typecheck, lint, and 27 automated tests passed; independent code, security, and product reviews approved the release.
