mx.api 0.2.0

• New transport endpoints for end-to-end-encryption coordination: mx_keys_upload(), mx_keys_query(), mx_keys_claim(), and mx_send_to_device(). The package itself remains crypto-free; these carry already-signed payloads built by an external signer (e.g. mx.crypto).
• mx_canonical_json() produces Matrix-spec canonical JSON, the byte sequence callers feed to their signer for /keys/upload.

mx.api 0.1.0

• Initial CRAN release.
• 19 exported functions covering the Matrix Client-Server API: login, register, logout, whoami, session reconstruction, room list, room create/join/leave, room members, room name/topic, message send and history, read receipts, reactions, sync, and media upload/download.
• End-to-end encryption is out of scope.
