Consolidates all alpha and unreleased features for internal validation ahead of the public 0.3.0 launch.

What's New

Multi-Founder LLM Extraction Fix (#354) — Unmatched relation subjects/objects now produce synthetic UNKNOWN entities instead of being silently dropped; all LLM-returned co-founders preserved
Reasoner Pattern Matching Rewrite (#354) — _match_pattern correctly handles multi-word values, pre-bound variables, repeated variable backreferences, and non-greedy separators

RDF / TTL Alias Fix (#355) — format="ttl", "nt", "xml", "rdf", "json-ld" all resolve without breaking existing callers
ArangoDB AQL Export (#342) — Full AQL INSERT generation for vertices and edges; configurable batching; 17 tests passing
Apache Parquet Export (#343) — Columnar storage with configurable compression (snappy, gzip, brotli, zstd, lz4); explicit Arrow schemas; 25 tests passing

Candidate Generation v2 (#338) — blocking_v2 / hybrid_v2 strategies with multi-key and phonetic blocking; 63.6% faster worst-case
Two-Stage Scoring Prefilter (#339) — Fast prefilter gates before expensive semantic scoring; 18–25% faster batch processing
Semantic Deduplication v2 (#340) — Opt-in semantic_v2 with canonicalization, O(1) hash matching, weighted scoring; 6.98x speedup; fixed infinite recursion bug
Migration Guide (#344) — MIGRATION_V2.md with full examples; 5.86x speedup confirmed; backward compatible

Delta Processing (#349) — Native SPARQL delta computation between graph snapshots; delta_mode pipeline config; prune_versions() for snapshot retention; production-ready for near real-time pipelines

NameError — missing Type import in utils/helpers.py; removed unused import from config_manager.py
Context module — fixed retrieve_decision_precedents, hybrid_retrieval, dynamic_context_traversal, multi_hop_context_assembly, _retrieve_from_vector, _extract_entities_from_query; added missing expand_context and _get_decision_query methods
Knowledge Graph module — fixed calculate_pagerank, community_detector._to_networkx, detect_communities, _build_adjacency; added ProvenanceTracker and 9 domain-specific tracking methods
Pipeline module — fixed retry loop in execution_engine; added RecoveryAction with LINEAR / EXPONENTIAL / FIXED backoff; fixed add_step return value; added validate alias
Test files — replaced emoji with ASCII for Windows cp1252 compatibility; fixed assertion ordering and loop bugs across 4 test files
