Populate ErrorRateChange before rendering it.
The supplied CalculateImprovements implementation initializes ErrorRateChange and returns without adding entries. This condition therefore stays false for PR-generated data, and kiro-krew eval diff never displays the required error-rate deltas. Calculate and store per-agent error-rate changes before this rendering path, then add a diff test with a nonzero delta.

Do not render a zero-baseline gain as 0.0%.
When firstScore is zero and lastScore is positive, the indicator is ↑ but percentChange remains 0.0. A relative percentage is undefined for a zero baseline. Display N/A with an absolute score-point delta, or use score-point deltas consistently.

Pull request overview
This PR adds baseline-based improvement tracking to the evaluation subsystem so eval runs can quantify changes over time (e.g., accuracy deltas), and exposes this via enhanced diff output plus new trend/report CLI commands.
Changes:
- Extended eval result types to persist
baseline_commitandimprovement_datainsummary.json. - Added new improvement/trend/report logic (and a large accompanying test suite) under
internal/eval/. - Updated
kiro-krew evalCLI to support baseline setting and newtrend/reportsubcommands, and enhancedeval diffoutput to show improvement indicators when available.

- SetBaseline validates the provided value by looking for an exact hash match in the eval results directories, but the CLI/help text and examples indicate refs (e.g. "main") may be used.

Summary
This PR implements improvement tracking for quantified evaluation metrics to meet Stage 3 AI maturity requirements. The feature enables measurement of accuracy gains (%) and error rate reductions (count) between evaluation runs through baseline comparison tracking.
