Cover the remaining paths in the client, context, downloads, title
generation, document tools and store models, and add fail_under=100 so
uncovered lines fail CI.
Six lines that no test can reach get a pragma with its reason: the docling
import guard, the nameless PDF attachment, the FS symlink OSError guard that
resolve(strict=False) absorbs, the docling bbox and LanceDB document-id
shape guards, the tag-retention branch vacuum makes unreachable, and Monty's
Rust-thread print callback.
Fix test_find_config_file_user_config, which wrote its config into the cwd it
had chdir'd to, so the cwd branch answered first and the user-directory
lookup it names was never exercised.
Parametrize sibling tests that differed only in a literal value, and fold
two strict-subset tests into the survivors that already covered their
scenario. Every case that ran before still runs; the union of assertions
is applied to each case, strengthening list_all, get_pages_data and
resolve_doc_items.
Replace four hand-rolled log-capture handlers with a shared
capture_logs() contextmanager in conftest.
13 fewer test functions, 348 fewer lines.
