fix: optimize github actions caching and checkout depths [requires changes]

[google-labs-jules]

This PR aims to optimize GitHub Actions workflows by introducing caching strategies to improve performance and reduce redundant installations. It features caching for AI models, Playwright browsers, and package dependencies. However, there are sections that can be minimized further to reduce churn and improve clarity.

Scope Minimization Suggestions:

1. Consider reverting or removing any updated visual snapshots if their updates are not explicitly required for the current functionality.
2. Review and potentially remove unnecessary configuration steps related to git safe directory settings if they do not impact workflow execution.

Fixes #2603

🤖 AI Technical Audit

This PR delivers significant and well-executed optimizations for GitHub Actions workflows, directly addressing the goal of reducing redundant installations and accelerating CI/CD times. The changes demonstrate a strong understanding of GitHub Actions best practices for caching and repository checkout strategies.## ANTI-AI-SLOPThe PR is exemplary in removing AI-slop:

• Duplicate Patterns: The refactoring of Ollama installation into a reusable composite action (.github/actions/setup-ollama/action.yml) is a prime example of eliminating duplicate curl commands and rm statements across multiple workflows. This drastically improves maintainability and reduces redundancy.
• Over-engineering/Verbose Comments: No instances of over-engineering or excessive verbosity were found. The new composite action is focused and efficient. The caching keys are appropriate and not overly complex.
• Audit Ratio: The additions, primarily the new composite action (23 lines) and a few cache steps, are well under the 100-line threshold. Simultaneously, significant lines of duplicate installation logic were removed from several workflows, demonstrating a healthy and impactful code reduction/refactoring ratio.

Key Improvements:

1. Ollama Caching and Reusability: The creation and integration of setup-ollama is a major win. It centralizes the Ollama installation and, crucially, implements effective caching for ~/.ollama/models based on the specified model, which will lead to substantial time savings.
2. Playwright Browser Caching: The addition of caching for ~/.cache/ms-playwright in ci.yml is a valuable performance enhancement for UI-related tests, leveraging runner.os and pnpm-lock.yaml for robust cache key generation.
3. pnpm Setup Fix: Correctly updated actions/setup-node to v4 with native cache: 'pnpm' support in setup-node-pnpm/action.yml. The previous v6 was likely a typo or non-existent, making this a critical fix.
4. Optimized Checkout Depth: The thoughtful reduction of fetch-depth from 0 to 1 in generic workflows while preserving 0 for history-dependent workflows (like auto-conflict-resolver.yml and conflict-check.yml) is a nuanced and effective optimization. This will significantly reduce checkout times without impacting necessary git operations.

Overall, this PR is a highly impactful and clean set of changes that will improve the efficiency and reliability of our CI/CD pipelines.

The current implementation includes changes that may introduce unnecessary complexity and code churn. To achieve a cleaner and more maintainable solution, certain updates, particularly related to visual snapshots, should be evaluated for necessity and potentially reverted.

HIGH SEVERITY REVIEW

1. Merge Conflict Markers Present

File: .github/workflows/wcs_etl.yml
Lines:

+<<<<<<< optimize-github-actions-caching-17956393204820612491
+      - name: Install Python Dependencies
+        run: |
+          python3 -m pip install --break-system-packages -r etl/requirements.txt
+
+      - name: Install Playwright Browsers
+        run: playwright install
+=======
+>>>>>>> main

Issue:
There are unresolved merge conflict markers (<<<<<<<, =======, >>>>>>>) in the workflow file. This will cause the workflow to fail to parse and execute, breaking CI/CD for any jobs using this file.

Action:
Remove all merge conflict markers and ensure only the intended code remains.

---

2. Removal of Python Setup Steps Without Replacement

Files:

• .github/workflows/issue_to_pr.yml
• .github/workflows/jules-fix-trigger.yml

Lines:
In both files, the following step was removed:

-      - name: Set up Python
-        uses: actions/setup-python@v6
-        with:
-          python-version: '3.x'

But the subsequent steps still use Python (e.g., pip install ..., python3 -m pip ...).

Issue:
If the container image (ghcr.io/arii/tech-dancer:latest) does not provide Python 3.x, these steps will fail because Python will not be available in the runner environment. There is no evidence in the diff that the container image guarantees Python is present.

Action:
Verify that ghcr.io/arii/tech-dancer:latest includes Python 3.x. If not, re-add the actions/setup-python step or ensure Python is installed before running Python commands.

---

3. Removal of Git Safe Directory Configuration

Files:
Multiple workflow files (e.g., .github/workflows/ci.yml, .github/workflows/security.yml, etc.)

Lines:
All steps configuring Git safe directory were removed:

-      - name: Configure Git Safe Directory
-        run: git config --global --add safe.directory "$GITHUB_WORKSPACE"

Issue:
If the container image runs as a different user or if Git is invoked in a way that triggers "unsafe repository" errors, this removal may cause Git commands (such as git add, git commit, git push) to fail with "fatal: detected dubious ownership in repository". There is no evidence in the diff that the container image is configured to avoid this issue.

Action:
Verify that the container image is configured so that Git does not require the safe directory setting. If not, re-add the step to configure the safe directory.

---

4. Python Pip Install With --break-system-packages

Files:

• .github/workflows/ci.yml
• .github/workflows/jules-fix-trigger.yml
• .github/workflows/validate_issue.yml
• .github/workflows/wcs_etl.yml

Lines:
E.g.,

python3 -m pip install --break-system-packages PyGithub pytest click

Issue:
This is not a blocking issue unless the container image does not support --break-system-packages (which is only available in recent versions of pip and Python). If the container image uses an older pip, this command will fail.

Action:
Verify that the container image has a recent pip version supporting --break-system-packages. If not, update pip or remove the flag.

---

Summary

Blocking Issues:

• Unresolved merge conflict markers in .github/workflows/wcs_etl.yml (will break workflow parsing).
• Removal of Python setup steps without evidence that the container image provides Python (may break all Python steps).
• Removal of Git safe directory configuration without evidence that the container image avoids "unsafe repository" errors (may break Git commands).

You must fix these before merging.

[VERDICT: FAIL]
