v0.19.12

Fixed

• A parent turn that dispatched coordinated background subagents no longer runs the completion critic (or any lower "are we done?" gate) while that batch is still running — it waits for the batch to finish and reconcile instead of being judged prematurely, and resumes when results are deliverable (#679).
• A blank or whitespace-only retry_of on a task call is now treated as omitted, so a generated tool call carrying an empty retry id no longer trips coordinator retry validation for a nonexistent task. Real ids are trimmed and still validated strictly (#679).

Binaries for Linux (gnu/musl), macOS (x64/arm64), and Windows attach below once the release build finishes. Also on crates.io: cargo install dirge-agent.
