Fixes #15

Standalone CSV results and zero-result summaries previously lost checker identity and assessment time already present in JSON/HTML. Capture one UTC assessment timestamp for the run, retain it after interruption, and project tool/name/version/time into every CSV row. Rendering accepts an injected timestamp so all formats can represent the same instant. Rule dates and unknown evidence-collection time remain distinct; advisory classifications and exploitability=not_tested are unchanged.

Validation: safely reproduced missing CSV fields on current main; 36 offline synthetic tests pass, including four new regression tests for consistent formats/multiple rows, empty summaries, interrupted runs, metadata precedence and formula protection. CLI help, checksum and git diff --check pass. README/reference/implementation/example are aligned. No network scans, package execution or deployment. Hosted Copilot review and exact-head CI are required before merge.

Exact-head validation: signed e450b263133643ba1424ccaf419a201dee21a0cb passed all 12 hosted push/PR matrix jobs (Python 3.10/3.14 on Ubuntu, Windows and macOS), plus 36 local synthetic tests and CLI/help/checksum/whitespace checks.

Hosted Copilot gate remains unsatisfied. The documented copilot-pull-request-reviewer[bot] request was made through the GitHub connector and retried with REST; both returned success, but requested reviewers remain empty, no review_requested timeline event exists, and completed reviews/inline discussions are empty on readback. Time was allowed for asynchronous completion; silence is not approval. This PR remains unmerged pending a completed exact-head hosted review. No issue closure is claimed.
