Add p90 and p99 response time metrics

[itssimon]

Summary by cubic

Add p90 and p99 response time metrics across the CLI, docs, and DuckDB metrics table to improve latency analysis. The CLI now accepts response_time_p90 and response_time_p99 in the metrics list.

• Migration
  • Existing DuckDB databases are auto-migrated to add response_time_p90 and response_time_p99; no manual steps needed.

^{Written for commit b9b5c11. Summary will update on new commits.}

P1: This schema change is not backward-compatible for existing DuckDB files: `CREATE TABLE IF NOT EXISTS` won’t add the new columns, so DB writes can fail on upgraded clients.</violation>
