ducksemantics 0.1.0

• Added the first release of the DuckDB-native semantic graph, lexical grounding, dense retrieval, exact late-interaction, structured judgment, and benchmark APIs.
• Validated the complete HPO 2026-06-23 release: 19,836 active nodes, 50,029 aliases, 24,378 direct edges, and 202,740 materialized is_a closure rows. Full model runs persisted 19,836 EmbeddingGemma vectors and 182,884 native LFM2.5-ColBERT token vectors.
• Corrected OBO qualifier parsing, decoded escaped quoted text, and imported alternate identifiers. Full HPO parsing now leaves no dangling qualified is_a targets.
• Made graph writes transactional and idempotent, restored graph indexes after projection and closure replacement, and isolated late-interaction blocks by provider, subject kind, subject, and block identifier.
• Deduplicated lexical aliases per span and node while assigning unique IDs to ambiguous candidates. Structured judgments now require exact candidate coverage, valid confidence values, and replacements grounded in supplied candidates or graph context.
• Made embedding caches content- and provider-aware, atomic, resumable, and safe to refresh without deleting unrelated files.
• Registered S7 methods during namespace loading and tightened table, vector, token metadata, benchmark, and model-provider validation.
• Replaced causal pooled-state retrieval paths with native EmbeddingGemma and LFM2.5-ColBERT providers. DuckDB VSS/HNSW remains an optional dense candidate-generation layer.
• Removed the reticulate/FastHPOCR and Rfmalloc runtime surfaces. Ontology and local graph sources now share one graph schema and durable DuckDB vector storage.
