ADR-0133: A3's export write has no save dialog

Status: accepted

Context

tauri-plugin-dialog is a real dependency and capability-file addition for a defect fix; the downloads directory plus filename disambiguation (never overwrite, append (2)) gives correct behaviour without it. Revisit if a "Save As…" UX is explicitly requested

Decision

A3's export write has no save dialog

Evidence

src-tauri/src/lib.rs, src/ts/utils.ts
