chore: remove retired review automation

[ANcpLua]

Automated by ANcpLua/github-settings-automation with the authenticated REPO_SETTINGS_PAT_* account, so GitHub shows that account as the PR author. Removes retired Codacy workflow and config files, the old triage-bot workflow, and the retired coderabbit-autofix workflow. Per-repo .coderabbit.yaml config files are deliberately NOT touched.

📝 Walkthrough

Walkthrough

Two GitHub Actions workflow files were removed. The "CodeRabbit Autofix Trigger" workflow, which posted an autofix comment on PR open/synchronize events, was deleted. The "triage-bot" workflow, which queried unresolved review threads via GraphQL, applied auto-resolve rules, resolved qualifying threads, and posted summary comments, was also deleted. No source code, exported entities, or public interfaces were altered; only workflow automation configuration was removed.
