#5884: fix: curly lint errors and formal conformance fork permissions

## Summary - Adds curly braces to two single-line `if` statements that violate the recently enabled `curly` lint rule - `src/routing/resolve-route.ts:224` — parentPeerMatch early return - `src/agents/system-prompt.ts:61` — userTimezone guard clause - Wraps the `formal_conformance` workflow PR comment in a try/catch so it doesn't fail on fork PRs that lack write permissions Both lint errors are currently failing on `main`. The formal conformance failure affects all fork PRs. ## Test plan - [ ] `pnpm lint` passes - [ ] `pnpm test` passes (no behavior change) - [ ] `formal_conformance` job no longer fails on fork PRs 🤖 Generated with [Claude Code](https://claude.com/claude-code) <!-- greptile_comment --> <h2>Greptile Overview</h2> <h3>Greptile Summary</h3> This PR makes two small TypeScript changes to satisfy the newly enabled `curly` ESLint rule by adding braces around single-line `if` early returns in `src/routing/resolve-route.ts` and `src/agents/system-prompt.ts`. It also updates the `formal_conformance` GitHub Actions workflow to avoid failing on fork PRs without write permissions by wrapping the `github.rest.issues.createComment` call in a `try/catch` and logging a warning when commenting is not permitted. This keeps the job informational while still surfacing drift via uploaded artifacts and the final step summary. <h3>Confidence Score: 5/5</h3> - This PR is safe to merge with minimal risk. - Changes are narrowly scoped (curly-brace lint fixes and a workflow try/catch) and do not affect runtime logic beyond formatting; the workflow change only prevents non-critical permission failures on fork PRs. - No files require special attention <!-- greptile_other_comments_section --> _{(4/5) You can add custom instructions or style guidelines for the agent [here](https://app.greptile.com/review/github)!} **Context used:** - Context from `dashboard` - CLAUDE.md ([source](https://app.greptile.com/review/custom-context?memory=fd949e91-5c3a-4ab5-90a1-cbe184fd6ce8)) - Context from `dashboard` - AGENTS.md ([source](https://app.greptile.com/review/custom-context?memory=0d0c8278-ef8e-4d6c-ab21-f5527e322f13)) <!-- /greptile_comment -->
