C Kaustubh fd98b845ea fix(node): prevent reranker from keeping process alive (#3270 )

Fixes #3269.

## What I observed
Using a reranker in a hybrid query could keep the Node.js process alive
even after `table.close()` and `db.close()`.

## Root cause
The reranker callback bridge used a `ThreadsafeFunction` in referenced
mode, which can keep the event loop alive longer than intended.

## Minimal fix
- In `nodejs/src/rerankers.rs`, create the reranker callback TSFN in
weak mode (`.weak::<true>()`).
- Add a regression test in `nodejs/__test__/rerankers.test.ts` that
spawns a child process, runs a rerank query, and asserts the process
exits naturally.

## Validation
- Built Node bindings successfully.
- Ran targeted tests: `rerankers.test.ts` passes (including new
regression test).
- Pre-commit checks for changed files were run and clean.
