opencrabs 0.3.46

//! Pin the "I need to <verb>" / multilingual deferment-stall detection
//! added 2026-05-28.
//!
//! User report: model emitted
//!   "I need to read the actual code before writing concrete task descriptions."
//! and the self-heal phantom detector did not catch it. Same shape as
//! "let me read" / "I'll read" — pre-action narration with no tool call
//! in the same turn. The fix added "i need to X", "i have to X",
//! "i must X", "i should X" variants to every language's intent_phrases
//! and extended each language's line_start_re to catch them at line
//! start too.
