Add Tura harness and refresh stale catalog entry

[Yohjisakamoto]

What changed

• Adds Tura to data/projects.yaml under Reference Harness Implementations.
• Uses the root README's English positioning and a faithful Chinese translation.
• Refreshes Tura's stars snapshot to 93 from the live repository page.
• Regenerates the English and Chinese READMEs.
• Removes the AGENT.md entry, whose last update (2025-07-10) crossed the catalog's 12-month staleness limit and caused the structural verifier to fail.
• Commits generated verification reports through 2026-07-17.

Why Tura belongs

Tura: 16.7% better performance, 77.5% fewer rounds.

Tura is a local, open-source coding agent for developers who are tired of vague skill claims, token-saving extensions with no evidence, and agents that change a repository before understanding it.

Tura is an AGPL-3.0 local coding-agent harness with inspectable repository editing and command execution, explicit task state and task-scoped context, verification steps, CLI/TUI/GUI workflows, and reproducible long-horizon benchmark manifests.

Verification

• python scripts/render_readme.py
• python scripts/verify_catalog.py --skip-links (passed with no structural errors or warnings)
• git diff --check (passed)
• Full link verification was also attempted earlier; GitHub's anonymous API rate limit produced transient URL failures, so the committed reports use the supported --skip-links mode.

Checklist

• Link is reachable
• Category is correct
• Summary is concise and practical
• Mirrors render cleanly in both READMEs
• Structural verification passes
