The integration test guarded only on ping(), so a plain Redis (or an SSH-forwarded one) on
6379 passed the liveness check and then FAILED both tests on 'unknown command GRAPH.QUERY'.
Add a read-only GRAPH.LIST probe that identifies the service and skips with a distinct
message when the graph module is absent, so the test still runs (and can fail) against a
real FalkorDB but no longer breaks on a wrong service.
Adds FalkorDB as a sibling option to the existing Neo4j sink, selected via
`graphify export falkordb [--push redis://localhost:6379]`.
- New push_to_falkordb() in graphify/export.py mirrors push_to_neo4j; FalkorDB
is OpenCypher-compatible so the MERGE/SET upsert queries are identical.
- export falkordb subcommand wired in graphify/__main__.py (cypher.txt when no
--push, direct push otherwise). Auth is optional; target graph defaults to
"graphify".
- falkordb optional extra in pyproject.toml (and in the all extra).
- Tests: CLI cypher generation (CI-safe) + real-FalkorDB integration tests that
skip when no instance is reachable.
- README extras table + command reference and CHANGELOG updated.
