* fix(cli): multi-word and literal-wildcard search in odysseus-docs
odysseus-docs search wrapped the whole query in one `%{query}%` LIKE over title/current_content, so multi-word queries only matched the exact adjacent phrase and literal % / _ acted as SQL wildcards. Split on whitespace, AND per token, and escape LIKE wildcards with the shared escape_like_pattern() helper. Whitespace-only queries now match all documents, consistent with document-library search.
Fixes#2123.
Tests: tests/cli/test_docs_cli_search.py (5 tests; multi-word, %, _, backslash, whitespace); 4 fail pre-fix, 5 pass post-fix. tests/cli full suite: 82 passed.
* test(cli): name whitespace-query search test accurately
The test passes a whitespace-only query, not an empty one; the old name implied a different input. Behavior is unchanged.
