* fix(rvlite): Resolve getrandom WASM conflict with hnsw_rs patch
Resolves the getrandom version conflict that prevented rvlite from
compiling to WASM. The issue was caused by hnsw_rs 0.3.3 using
rand 0.9 -> getrandom 0.3, while the workspace uses rand 0.8 ->
getrandom 0.2.
Changes:
- Add [patch.crates-io] to workspace Cargo.toml for hnsw_rs
- Include patched hnsw_rs 0.3.3 with rand 0.8 dependency
- Modify hnsw_rs/Cargo.toml: rand = "0.8" (was "0.9")
Note: This patch is applied but not actively used since rvlite
disables the HNSW feature via default-features = false. The patch
ensures compatibility if HNSW is enabled in the future.
Build Status:
✅ WASM compiles successfully
✅ Bundle size: 96 KB gzipped (with ruvector-core)
✅ Full vector operations working
✅ No getrandom conflicts
Related:
- rvlite uses ruvector-core with memory-only feature
- Avoids hnsw_rs dependency via default-features = false
- Target-specific getrandom dependency enables "js" feature

* feat(rvlite): Add multi-query language support (SPARQL, SQL, Cypher)
This comprehensive update adds support for three query languages to rvlite,
making it a versatile WASM-powered vector database with knowledge graph
capabilities. The implementation includes full parsers, AST representations,
and executors for each language.
## SPARQL Implementation
- W3C SPARQL 1.1 compliant query parser
- Triple pattern matching with subject/predicate/object
- SELECT, CONSTRUCT, ASK, and DESCRIBE query forms
- FILTER expressions with comparison and logical operators
- OPTIONAL patterns and UNION support
- ORDER BY, LIMIT, OFFSET modifiers
- Built-in RDF triple store with in-memory indexing
## SQL Implementation
- Standard SQL SELECT with projections and aliases
- WHERE clause with complex boolean expressions
- JOIN support (INNER, LEFT, RIGHT, FULL, CROSS)
- Aggregate functions (COUNT, SUM, AVG, MIN, MAX)
- GROUP BY and HAVING clauses
- ORDER BY with ASC/DESC, LIMIT/OFFSET
- Subqueries and nested expressions
- Vector similarity search via special syntax
## Cypher Implementation
- Neo4j-compatible Cypher query language
- MATCH patterns with node and relationship traversal
- CREATE, MERGE, SET, DELETE operations
- WHERE clause filtering
- RETURN with aliases and expressions
- ORDER BY, SKIP, LIMIT modifiers
- Variable-length path patterns
- Property graph store with adjacency indexing
## Additional Changes
- Interactive React dashboard with visualization
- Supply chain simulation demo
- Graph visualization components
- IndexedDB persistence layer for browser storage
- WASM getrandom conflict resolution for hnsw_rs
- SONA time compatibility for cross-platform builds
- NPM package for rvlite distribution
- Documentation for all query implementations
