Summary

Makes baseline pruning evidence-based and safe by default.

• baseline prune now re-evaluates current diagnostics rather than removing entries based only on a persisted lifecycle field.
• Dry run is the default; --apply is required to write.
• Reports inspected, removable, removed and retained counts plus per-entry rule/path/lifecycle details.
• Refuses the entire write when structural/context matching is ambiguous, leaving the baseline unchanged.
• Keeps --include-fixtures available for reviewed baselines containing fixture findings.
• Adds unit coverage for dry-run behavior, explicit application, and ambiguity refusal.

Compatibility

• Baseline schema remains version 1.
• The command becomes safer: scripts that expected an implicit write must add --apply.
• Ambiguous matching is now a hard refusal instead of an unsafe cleanup.

Verification

• cargo fmt --all -- --check
• cargo clippy --workspace --all-targets --all-features -- -D warnings
• cargo test --workspace --lib --bins --tests
• Release CLI manual dry-run and --apply round trip
• Changed-file self-review with zero diagnostics
