Rewrite a2a-t-corpus/README.md and README_zh.md following the structure of the Python repository's corpus guide, adjusted to this module:

• Update the directory tree to the real layout (pom.xml, src/test engine/suites, actual task scenarios: private-line-complaint, ran-energy-saving-modify, backup-battery endurance create/modify)
• Move Notification-T (service-recovery, subscribe-incident) from "later phases" into the current coverage
• Replace run commands with Maven equivalents (-Dcorpus.scenario, -Dcase.filter, -Dcorpus.output.dir) and document LLM config resolution (system properties > .env > environment)
• Drop the non-existent tools/*.sh wrappers and update the summary report path to target/corpus/
• Present the case JSON contract as a top-level array, matching the schemas, and use private-line-complaint in the walkthrough
