Gergo Magyar a84645a4b1 fix(lbug): skip native close on CLI exit to dodge LadybugDB destructor double-free (#2264)
THE actual fix for the `analyze --pdg` crash. gdb shows the abort is a double-free
inside LadybugDB's own destructor during conn.close():

  "double free or corruption (out)" -> abort
    lbug::main::ClientContext::~ClientContext()
    lbug::main::Connection::~Connection()
    NodeConnection::Close(...)          <- conn.close() from safeClose

It reproduces with the WAL driver OFF and with serial load, so it is NOT the
checkpoint/COPY concurrency the rest of this branch serialized — it's a native
LadybugDB engine bug (@ladybugdb/core 0.17.1, latest stable) triggered by the
larger --pdg write set, firing during teardown AFTER a fully-written, checkpointed
index.

Fix: closeLbug({ skipNativeClose }) CHECKPOINTs for durability (flushWAL) then
skips conn.close()/db.close(), leaving the handles referenced so no GC finalizer
re-runs the destructor. The CLI analyze command (success, error, and SIGINT paths
all process.exit) opts in via skipNativeCloseOnExit; long-lived callers (MCP
server, tests) keep the real close. Mirrors the pool adapter's fire-and-forget
native close and the ONNX native-cleanup philosophy.

Validated end-to-end: `analyze --pdg --force` now exits 0 with a 193,876-node
index; re-opening it (no --force) reads clean and reports up-to-date, proving the
CHECKPOINT-only persistence is durable without db.close().

Workaround for an upstream LadybugDB bug (ClientContext destructor double-free).
