fix(notion-search): correct --filter example syntax in docs

Final review caught that both --filter example locations used simplified
JSON ({"Status": "Done"}) that Notion's data_sources.query API rejects
with a 400. The script passes --filter verbatim, so users copy-pasting
the example would hit a confusing error.

Replace with Notion's actual filter shape:
  {"property": "Status", "status": {"equals": "Done"}}

Also added a compound (and/or) example in CLAUDE.md so users have a
reference for combining filters.

30/30 tests still pass.
