eef6778839 fix: Resolve CI build failures
- Format all Rust code with cargo fmt
- Generate Cargo.lock for security audit
- Add build:wasm script to graph-wasm package.json
- Update npm/package-lock.json

The CI was failing due to:
1. Rust code formatting check failures
2. Missing Cargo.lock file for cargo audit
3. Missing build:wasm script expected by graph-ci.yml workflow

perf: Add benchmarks and optimize new capabilities
Benchmarks:
- Parser: simple_match, relationship, chained patterns (2/3/4 hop)
- Parser: map literals (empty/2/5/10 keys), REMOVE statements
- Parser: complex queries with multiple clauses
- Semantic search: scalability (100/1000 vectors), dimensions (64-512)
- Semantic search: top-k (1-100), distance conversion overhead

Benchmark Results (baseline):
- simple_match: ~4.9 µs
- relationship_match: ~16.7 µs
- chained 4-hop: ~28.1 µs (linear scaling ~5.5 µs/hop)
- map_literal 10-keys: ~48 µs (~4.4 µs/key)
- semantic_search 1000v: ~60 µs
- distance_conversion: ~38 ps (negligible)

Optimizations:
- Pre-allocate HashMap with capacity(8) for map literals
- Pre-compute max_distance threshold in semantic search
- Replace iterator chain with explicit loop + Vec::with_capacity
- Filter by distance instead of converting then comparing

All 136 tests pass, 3 ignored

- Now correctly returns all nodes reachable within k hops

Test results:
- 285 tests passing
- 12 tests ignored (infrastructure/edge cases)

Ignored tests are for:
- Vector embedding pipeline infrastructure (semantic search, RAG)
- Parser edge cases (empty query, whitespace, map literals)
- Million node performance test

fix: Resolve compilation errors in ruvector-graph crate
This commit fixes multiple compilation issues in the Neo4j-compatible
hypergraph database implementation:

Build Fixes:
- Add Hash, Eq derives to Label type for HashMap compatibility
- Fix PropertyValue enum - add List variant as alias for Array
- Fix LabelIndex to use label.name instead of Label struct as key
- Split cypher lexer alt() into nested calls (nom 21-alternative limit)
- Fix RoaringBitmap serialize method (use serialize_into)
- Add ordered-float dependency for Hash impl on float values
- Fix ReadOnlyTable usage (use iter().count() instead of len())
- Add VectorIndex trait import for HnswIndex methods
- Fix PropertyValue variant names in match statements (Boolean/Integer)
- Add Clone bound to AdaptiveRadixTree generic parameter
- Fix PhysicalPlan to use custom Debug impl (dyn Operator not Clone)
- Add HyperedgeScan to PlanNode compile_node match

Type System:
- Implement Hash and Eq for plan::Value using OrderedFloat
- Fix property_value_to_string to handle all PropertyValue variants
- Add proper type annotations for nom parser combinators

Code Quality:
- Remove unused Clone derive from PhysicalPlan
- Use std::mem::take for ownership transfer in Pipeline
- Fix ArtNode type annotation in adaptive_radix.rs
- Clean up test_cypher_parser.rs to use library import

The library now compiles successfully. Some test files still need
updates for NodeBuilder/EdgeBuilder exports and From implementations.

- NPM packages for both targets

## CLI Integration
- 8 new graph commands: create, query, shell, import, export, info, benchmark, serve

## CI/CD
