OSS restructuring for open-core model: - Rename package from agentserver/ to xml_pipeline/ - Update all imports (44 Python files, 31 docs/configs) - Update pyproject.toml for OSS distribution (v0.3.0) - Move prompt_toolkit from core to optional [console] extra - Remove auth/server/lsp from core optional deps (-> Nextra) New console example in examples/console/: - Self-contained demo with handlers and config - Uses prompt_toolkit (optional, falls back to input()) - No password auth, no TUI, no LSP — just the basics - Shows how to use xml-pipeline as a library Import changes: - from agentserver.* -> from xml_pipeline.* - CLI entry points updated: xml_pipeline.cli:main Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
