feat(managed): add retained metadata overview and pages (#2413)

Add caller-selected managed metadata summaries and original collection pages while preserving complete CLI/MCP defaults and previous-runtime Evidence. Real SDK replies shrink substantially; actual Codex token/latency results remain mixed and are documented without a token-saving claim.

Validated focused SDK/domain tests, full static/docs checks, real two-assembly repeated workflows and portable old Evidence, real SQLite WASM, and all exact-head CI checks. Raw experimental artifacts remain private.
