v0.12.14

Summary

• Restores self-validation by default, but only for high-risk final answers.
• Adds self_validate_risk_only so callers can force validate-every-final behavior when needed.
• Shortens the validation prompt to reduce the cost of validation turns.
• Updates the v0.12 plan with the 0.12.13 eval result and 0.12.14 adjustment.

Motivation

0.12.13 removed validation turns and reduced cost/steps, but success fell from 140/198 to 132/198 and Incorrect Result failures increased from 16 to 24. Validation was expensive, but it was catching real bad finals. This release restores validation selectively for search/filter/sort/locator tasks, counted top/first/list tasks, recency/current/latest tasks, price/date/availability/fare tasks, and blocked/external-evidence finals.

Dry-run over the 0.12.13 traces estimates validation would apply to about 73 successful step>=3 tasks, versus 102 provisional finalization turns in 0.12.12.
