opencrabs 0.3.58

//! Tests for `utils::image::extract_react_marker` — the `<<react:emoji>>`
//! reaction directive extractor.
//!
//! The extractor is strict on purpose: only payloads that look like a real
//! emoji are treated as directives, and occurrences inside backtick code
//! spans are never extracted. A word payload (`<<react:emoji>>` written in
//! prose while discussing the feature) once fired a bogus REACTION_INVALID
//! Telegram call and mutated the final text, breaking exact-match dedup
//! against the already-sent intermediate — both copies landed in the chat.
