laposte-cli

Send registered (LREL) or priority (LEL) French postal mail via laposte.fr from the terminal using `laposte_cli`. Use when the user wants to send a paper letter, a recommandé/AR, an e-lettre rouge, or upload one or more PDFs for La Poste to print + distribute. The CLI uploads PDF(s), RNVP-certifies recipient address(es), creates a cart entry, then opens https://www.laposte.fr/checkout/recapitulatif so the user can confirm payment in the browser with a saved card. Cookies are read live from the user's browser — no manual paste, no API key.
