nester-neo4j 81d05053b2 feat: Neo4j tools enhancements - neo4j-execute-cypher (#946) ...

This pull request introduces a new tool for executing arbitrary Cypher
queries against a Neo4j database (`neo4j-execute-cypher`) and implements
robust query classification functionality to distinguish between read
and write operations. The changes include updates to documentation, the
addition of a query classifier, and comprehensive test coverage for the
classifier.

### Addition of `neo4j-execute-cypher` tool:

- **Documentation**: Added a new markdown file `neo4j-execute-cypher.md`
that explains the tool's functionality, usage, and configuration
options, including the ability to enforce read-only mode for security.
- **Import statement**: Registered the new tool in the `cmd/root.go`
file to make it available in the toolbox.

### Query classification functionality:

- **Query classifier implementation**: Added `QueryClassifier` in
`classifier.go`, which classifies Cypher queries into read or write
operations based on keywords, procedures, and subquery analysis. It
supports handling edge cases like nested subqueries, multi-word
keywords, and invalid syntax.
- **Test coverage**: Created extensive tests in `classifier_test.go` to
validate the classifier's behavior across various query types, including
abuse cases, subqueries, and procedure calls. Tests ensure the
classifier is robust and does not panic on malformed queries.
