Implement two virtual node patterns for message flow orchestration:
- Sequence: Chains listeners in order (A→B→C), feeding each step's
output as input to the next. Uses ephemeral listeners to intercept
step results without modifying core pump behavior.
- Buffer: Fan-out to parallel worker threads with optional result
collection. Supports fire-and-forget mode (collect=False) for
non-blocking dispatch.
New files:
- sequence_registry.py / buffer_registry.py: State tracking
- sequence.py / buffer.py: Payloads and handlers
- test_sequence.py / test_buffer.py: 52 new tests
Pump additions:
- register_generic_listener(): Accept any payload type
- unregister_listener(): Cleanup ephemeral listeners
- Global singleton accessors for pump instance

Introduces SharedBackend Protocol for cross-process state sharing:
- InMemoryBackend: default single-process storage
- ManagerBackend: multiprocessing.Manager for local multi-process
- RedisBackend: distributed deployments with TTL auto-GC
Adds ProcessPoolExecutor support for CPU-bound handlers:
- worker.py: worker process entry point
- stream_pump.py: cpu_bound handler dispatch
- Config: backend and process_pool sections in organism.yaml
ContextBuffer and ThreadRegistry now accept optional backend
parameter while maintaining full backward compatibility.

Use __file__-based path resolution for envelope.xsd so the schema
loads correctly when xml-pipeline is installed via pip.
Also:
- Add build artifacts to .gitignore
- Bump version to 0.3.1

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
