Summary

This PR expands governance benchmark coverage with dedicated query/read and materialization suites.

Highlights

Query and read benchmarks

• Measure pending request list lookup.
• Measure pending approval queue lookup.
• Measure recent decision and execution outcome lookup.
• Keep query helpers local to the benchmark project.

Materialization benchmarks

• Measure history entry materialization from governed execution output.
• Measure audit entry materialization from governed execution output.
• Measure decision view materialization for downstream consumers.
• Keep side effect and output shaping visible in isolation.

Why

Issues #78 and #79 ask for benchmark visibility into governance read paths and output materialization.

These suites extend the governance benchmark umbrella #73 so request listing, approval lookup, decision projection, and output materialization stay visible without folding them into broader runtime measurements.
