* fix(api-contract): retain partial OpenAPI evidence
* docs(api-contract): describe partial OpenAPI Evidence on interruption
Early failures still keep the file snapshot hash. Cancellation or the
retained-facts limit after a row now returns authenticated Evidence, and
the guide explains how to reuse that partial inventory.
* fix(api-contract): count finished paths and keep earlier diagnostics
A path counts only after its item is read, so a path refused before
traversal does not increase path_entries_examined. A paths diagnostic
that exhausts the retained-facts allowance still keeps diagnostics
already stored, including invalid info.
* test(api-contract): keep invalid info when paths exhaust the allowance
The paths diagnostic can fail after invalid info is already stored. The
partial report must still carry that diagnostic and count no path entries.
* docs(api-contract): name every retained row and the view source
The hash remains only when no operation, reference, or diagnostic row was
kept. Partial Evidence is reread through inspect_analysis_view's source
and view, not as separate Evidence fields.
* test(api-contract): verify interrupted inventory evidence
