Add durable tabular Analyze and Search parity

[Paul Lizer (paullizer)]

Summary

• Route exhaustive tabular Search and Analyze requests through a shared, route-neutral durable preflight planner.
• Preserve truthful pending, failed, canceled, and completed evidence across pure tabular, mixed-source, per-document, and multi-table workflows.
• Add deferred mixed-source composition, public lifecycle coverage, backend-only shadow/canary controls, privacy-safe telemetry, and legacy fallback retirement controls.
• Reuse existing authorization, source-version validation, rollback, durable runner, and artifact-card contracts.
• Add consolidated release notes and bump the application version to 0.250.166.

Rollout

The shared planner and Search/Analyze adapters remain controlled by backend-only settings. Operators can keep planner mode off, compare decisions in shadow mode, canary active traffic by percentage, and retain or retire the legacy post-tool fallback independently.
