feat: enhance Lucene query parser to support full Apache Lucene syntax

Implements comprehensive Apache Lucene query parser syntax support as specified
in https://lucene.apache.org/core/2_9_4/queryparsersyntax.html

- **Quoted phrases**: "hello world" for exact matching
- **Alternative boolean operators**: && (AND), || (OR), ! (NOT)
- **Required operator**: +term (must match)
- **Prohibited operator**: -term (must not match)
- **Range queries**: [min TO max] (inclusive), {min TO max} (exclusive)
- **Open-ended ranges**: [18 TO *], [* TO 100]
- **Date ranges**: [2024-01-01 TO 2024-12-31]
- **Wildcard searches**: Enhanced support for *, ? patterns
- **Grouping**: Complex nested boolean expressions
- **Special character handling**: Backslash escaping support

- New lexer (lexer.go) for proper tokenization of all Lucene operators
- Enhanced parser (parser_new.go) with recursive descent parsing
- Comparison operators support (>, <, >=, <=) for range queries
- Automatic parser selection based on query syntax
- Backward compatibility with existing simple queries

- **SQL**: Generates parameterized WHERE clauses with comparison operators
- **DynamoDB PartiQL**: Converts to PartiQL with range support
- **Map format**: Preserves all query semantics for custom backends

- Comprehensive test suite (parser_test.go) with 60+ test cases
- Tests for all new operators and syntax features
- Performance benchmarks included
- Coverage for edge cases and complex nested queries

- Complete README with usage examples
- Feature matrix showing supported syntax
- Backend compatibility notes
- Performance characteristics
- Known limitations documented

```go
// Range queries
"age:[18 TO 65] AND status:active"

// Alternative operators
"(name:john || name:jane) && !status:inactive"

// Quoted phrases with wildcards
`title:"Apache Lucene" AND email:*@example.com`

// Complex nested queries
"(name:john* OR email:*@example.com) AND age:[25 TO *]"
```

- Zero breaking changes to existing API
- Enhanced parser auto-selected for advanced syntax
- Legacy parser maintained for simple queries
- Best-effort conversion for backends without native support
- Range queries converted to comparison operators in SQL
- Fuzzy/proximity searches approximated with wildcards
