B5: Codeac analyze results fails on every PR — analysis crash from A1 invalid JSON (+ commit processing timeout)

[arena-ai-coding-agent]

Audit follow-up. The Codeac analyze results check (Codeac GitHub App) fails on every PR (e.g. PR #81). It is not a required context — PRs merge anyway — but it is permanent red noise.

Findings (from the Codeac analysis page for the last commit + Codeac's own docs at codeac.io/documentation/thresholds.html):

1. The fail state is an analysis crash, not findings. Codeac docs: "If the threshold is not specified, Codeac will signal a success to all commits with finished analysis. The failed state is used only when the whole analysis fails, for example with configuration issues or other errors." — this repo has no .codeac.yml thresholds, so its ~31k findings alone would still report success.
2. The crash: ESLint 8.57.1 aborted on praxis/SymbolicEngine/graphql/package.json — Error: Expected double-quoted property name in JSON at position 1399 — i.e. exactly issue A1: praxis/SymbolicEngine/graphql/package.json is invalid JSON (trailing comma after "bun-types") #82's invalid JSON. Plus "Processing of this commit timed out."

So: fixing #82 removes the ESLint crash and is the in-repo fix for this check. The residual risk is the processing timeout on this monorepo's volume.

It IS configurable: per-tool native configs (ESLint, PHPMD, SCSS Lint, jscpd via .jscpd.json, ignore files like .codesizeignore), and optional .codeac.yml thresholds. But the analysis set (phpmd clean-code rules like CamelCase* on WordPress-style PHP, scsslint style rules on journal-theme) will keep producing thousands of style findings this codebase will never "fix", and taming that means maintaining several suppression configs.

Recommendation: fix #82 and re-check on the follow-up PR. If analysis still times out or keeps failing for tool crashes, disable it (uninstall the Codeac GitHub App or at least keep it out of required contexts) — it duplicates CodeFactor + Semgrep + GitGuardian + Hypatia Security Scan + gitleaks, which all pass here.

Verification plan: watch this check on the fixing PR; close this issue if it goes green after #82 lands.
