Frecency parser crashes on JSON null entries

Description

The TUI frecency parser accepts any syntactically valid JSON value as a frecency entry. If frecency.jsonl contains null, parsing reaches the deduplication step and reads entry.path, which throws TypeError: null is not an object. As a result, file autocomplete frecency state cannot finish loading. Invalid entries should be skipped while valid neighboring entries are retained.

Steps to reproduce

1. Add a line containing only null to the TUI state file frecency.jsonl.
2. Start the TUI, or call the frecency parser with null\n.
3. Observe TypeError: null is not an object (evaluating 'entry.path').

Expected: malformed entries are ignored and valid entries still load.

Actual: parsing throws before frecency state is initialized.
