Version v0.4.5 hardens writable file locking to prevent concurrent writers from corrupting `.rememb/entries.json`.

Why it matters: Patch to v0.4.5 immediately if your workload writes concurrently to `.rememb/entries.json` to avoid data corruption.

Full changelog

Highlights

Prevented concurrent writers from corrupting .rememb/entries.json during large delete and consolidation operations.
Hardened writable file locking so every mutating mode, including r+, is treated as an exclusive write lock.
Added a regression test that proves a second process cannot acquire a writable lock while another write operation is still in progress.

Included changes

fix: treat mutating file modes as exclusive locks in the storage helper
test: cover r+ write-lock exclusivity with a multiprocessing regression test
chore: bump package and release metadata to 0.4.5

Validation

Ran pytest tests/test_store.py -q
Ran python -m py_compile src/rememb/*.py tests/test_store.py
Built wheel and sdist with python -m build
Verified package metadata with python -m twine check dist/*
