pdf_oxide_cli 0.3.51

//! `pdf-oxide auto <file> [--format text|json]` — auto-extract text:
//! per-page text-vs-OCR routing with graceful native fallback (never
//! the opaque OCR error — #513). `text` = assembled; `json` = rich
//! per-region `PageExtraction` with typed reasons (#517).
//!
//! Strictly additive — the existing `text` command is untouched.
