cairn-lang (compatibility shim)

cairn was split into two packages in v0.9:

• deborah — the process language (spec, grammar, conformance, render).
• huldah — human-systems analysis (human factors, UI evidence, layout load, live observation, agent harness).

This package keeps import cairn working, re-exporting every pre-split name from its new home with a DeprecationWarning. Submodules resolve too, including deep paths (cairn.grammar.parser).

It depends only on deborah. If you used the analysis half, install huldah as well (or pip install 'cairn-lang[analysis]') — otherwise those names raise an ImportError naming the package to install.

The document format is unchanged: .cairn.md files and ```cairn fences still work exactly as before. Only the Python distributions were renamed.

Scheduled for removal one minor release after the last consumer migrates. See MIGRATING.md.
