When a CLI report had no baseline or artifact URL, its Markdown promised future main-branch deltas and claimed a coverage-summary upload. A run URL alone was also omitted.

The renderer now describes the missing baseline without CI assumptions, omits artifact claims without an explicit URL, and renders run links independently. Existing explicit full-summary artifact links retain their label. The PR-build workflow adds the actual uploaded artifact URL to its comment and run summary, labeled as LCOV and Markdown. The archived report keeps its run link because the artifact URL becomes available after upload. Reference, example and contributor documentation explain the behavior; no new flags or public fields are introduced.

Closes #137

Implementation plan: #137 (comment)

Verification (all passed locally and repeated after rebase onto current origin/main; commands explicitly targeted this worktree):

• cargo fmt --check
• actionlint .github/workflows/ci.yml
• cargo test --locked render::tests — 34 renderer tests, including missing baseline and all absent/empty/supplied URL combinations
• cargo test --locked --all-targets — 541 tests
• cargo test --locked --doc
• cargo clippy --locked --all-targets -- -D warnings
• cargo run --locked -- lint-markers
• cargo +1.88.0 test --locked --all-targets
• cargo +1.88.0 test --locked --doc
• RUSTDOCFLAGS='-D warnings' cargo doc --locked --no-deps --document-private-items
• cargo test --locked --test doc_links_test — 13 passed after the review fix

Review: inspected the committed diff and surrounding renderer/workflow code once. Fixed the stale baseline notice in README.md:60 in a separate commit. No findings skipped, unrelated follow-ups, or departures from the plan. Hosted artifact upload/comment behavior and Linux/Windows execution require GitHub CI; fork-token behavior was not exercised locally.
