FIX: Respect Joblib context in config sync (Issue #76)

[ANJAN672]

Fixes #76 (partial)

Problem

When using joblib.parallel_config(n_jobs=X), nx-parallel was ignoring the value and always using nx.config.backends.parallel.n_jobs.

Solution

• Modified decorators.py to peek at Joblib's active context before overriding
• Modified chunk.py to prioritize Joblib's active value over NX config

Known Limitation

When NX context is nested inside Joblib context, Joblib still wins. Full sync requires upstream changes to both libraries.

Tests

All 89 existing tests pass.

Thanks for the PR @ANJAN672 !

you can change that by setting active=False in nx.config , read - https://github.com/networkx/nx-parallel/blob/main/Config.md

Also read - #76 (comment) -- And please consider closing this PR if you agree with it. Thx!
