Update AI workflows to match upstream patterns

[strawgate]

Summary

• Align AI GitHub Actions workflows with patterns from ai-github-actions-playground
• Add new valuable workflows for library maintenance
• Remove deprecated workflows not present in upstream

Changes

Updated workflows:

• PR Review: use pull_request_target for security, add author association check, use intensity/minimum_severity params
• Mention in PR/Issue: use -no-sandbox variants, remove setup-commands/messages-footer
• Minimize Resolved Reviews: simplify triggers to just pull_request_review, add concurrency group
• Bug Hunter, Issue Triage, Stale Issues: fix permissions, use title-prefix
• Docs Drift → Docs Patrol: rename file, update permissions
• PR Actions Fixer → PR Actions Detective: add gate job with label check

New workflows:

Workflow	Purpose
Breaking Change Detector	Detect API breaking changes (valuable for library)
Duplicate Issue Detector	Identify duplicate issues on open
Address PR Review Feedback	Auto-fix minor bot review feedback
Refactor Opportunist	Identify refactoring opportunities
Code Duplication Detector	Find duplicate Python code

Removed workflows (not in upstream):

• Small Problem Fixer
• Code Simplifier
• Test Improvement

Test plan

• Verify workflows pass YAML validation
• Test PR Review workflow on a test PR
• Test Mention workflows with /ai command

Note

Update AI GitHub Actions workflows to match upstream patterns

• Adds several new AI workflows: address PR review feedback, breaking change detection, code duplication detection (Python), docs patrol, duplicate issue detection, and a refactor opportunist (weekly).
• Adds a PR Actions Detective workflow that triggers on test failures and comments on the failing PR unless the no-pr-actions-detective label is set.
• Updates the PR review workflow to use pull_request_target, switch the opt-out label to no-pr-review, and apply aggressive intensity with nitpick minimum severity.
• Switches mention-in-issue and mention-in-pr to the no-sandbox reusable workflow variants and removes setup-commands/messages-footer inputs across multiple workflows.
• Removes four workflows: Code Simplifier, Docs Drift, PR Actions Fixer, Small Problem Fixer, and Test Improvement.
• Updates minimize-resolved-reviews to trigger only on PR review submission with concurrency control, dropping the /tidy comment gate.
• Reduces permissions in trigger-bug-hunter from write to read and replaces its inputs with a title-prefix.
