opencrabs 0.3.58

//! Regression: the phantom self-heal must catch a brief present-continuous
//! work announcement that ends the turn with no tool call.
//!
//! 2026-06-12: mimo-v2.5-pro replied just "Running checks now." (19 bytes),
//! emitted zero tool calls, and the turn dropped. The no-tools detector
//! early-returned at its `len() < 20` floor, so it never examined the text.
//! These announcements are now matched before the floor via a per-language
//! `work_announcement_re`, anchored and requiring an imminence marker (now /
//! ahora / agora / maintenant / сейчас / … / : ) so ordinary sentences that
//! merely open with a gerund are NOT flagged.
