v0.12.0

What's New

Claude Code Backend

Pluggable AgentBackend interface with --backend claude-code flag. Spawns the claude CLI as a subprocess, parses NDJSON output, and maps exit codes to pipeline outcomes. Per-node via backend: claude-code in .dip files, or global via CLI flag. Includes environment scoping, token tracking, and retryable init.

Self-Update

tracker update downloads the latest release, verifies SHA256 checksum, smoke-tests the binary, and atomically replaces with .bak rollback. Detects install method (Homebrew/go install/binary) and advises accordingly. Non-blocking update check runs on every tracker run (24h cache).

dippin-lang v0.12.0

Upgraded from v0.10.0 — picks up preferred_label on freeform gates, immediately_after assertions, tool command lint rules, subgraph validation, and dippin test --coverage.
