v0.2.0 - Quality, token, and duration PR reporting

Quality, token, and duration reporting prerelease

Surfaces quality scores, duration, token usage, and per-case outcomes in sticky PR reports and workflow job summaries so authors and marketplace maintainers can review skill improvements at a glance.

Highlights

• Adds a compact Quality & token summary table (Passed, Failed, Avg Score, Total Tokens, Total Duration) to sticky PR reports and job summaries when trial metrics are recorded.
• Surfaces per-case quality score percentages, durations, token usage (in/out), and failed check details directly in the ### Evals table and expandable failure details.
• Preserves existing lint/run/report contracts and zero-leakage handling when optional metrics are absent.
• Includes open-source readiness, contribution terms, license alignment, and Vally telemetry preservation updates (#12, #13, #14, #18, #20, #21, #24).
