fix(mcp): return complete inline Evidence records (#585)

Return complete canonical Evidence records inline, including normalized_result, and preserve direct comparison and retained bundle identity.

Verified full deterministic gate, real Linux Ghidra CLI/MCP and independently installed artifact, generic package acceptance, private local samples, and targeted updates after syncing main.

Closes #551
