Improve symbol matching in graph queries and enforce JSON output

[m1rl0k]

In context_search.py, force output_format="json" for internal repo_search to ensure consistent result parsing. In neo4j_graph.py, enhance all symbol-matching queries to also support suffix matching for symbols stored with full module paths, improving accuracy for class and method lookups.

Summary: Improves context search result consistency and Neo4j graph symbol resolution.

Changes:

• Forces internal repo_search calls in context_search.py to use output_format="json" to keep downstream parsing stable.
• Updates Neo4j graph queries to match symbols by suffix as well as exact/prefix, so unqualified names can resolve to fully-qualified module-path symbols.

Technical Notes: Adds ENDS WITH checks and threads a symbol_suffix parameter through direct and transitive traversal helpers for callers/callees/dependencies/cycles.
