Updates to Agent_00.

Fixed task history display so merged tasks stay with active work, completed history dedupes against running tasks, and same-task reordering waits for the delayed sync window instead of jumping.

Improved failure-result publishing and agent setup by extending the local failure publish timeout, preserving retry behavior, staging AGENTS prompts without writing target files, and seeding Railsmith Codex guidance at startup.

Improved the local dashboard and Prompt Studio with D3 task chart icon legends that omit duplicate counts, plus native manual resizing for builder and raw JSON prompt textareas.
