Fix Claude Code workflow permissions

[BenGWeeks]

Issue: Claude Code Workflow Permission Mismatch

The Claude Code GitHub Actions workflows have insufficient permissions that will prevent them from functioning correctly.

Affected Files

1. .github/workflows/claude.yml
2. .github/workflows/claude-code-review.yml

Problems

In claude.yml:

• Currently has: contents: read, pull-requests: read, issues: read
• Needs: contents: write, pull-requests: write, issues: write
• Why: Claude needs write permissions to create comments, branches, and commits as described in the workflow documentation

In claude-code-review.yml:

• Currently has: pull-requests: read
• Needs: pull-requests: write
• Why: The workflow instructs Claude to use `gh pr comment` which requires write permission to post review comments

Solution

Update the permissions in both files:

For claude.yml, change:
```yaml
permissions:
contents: write
pull-requests: write
issues: write
id-token: write
actions: read
```

For claude-code-review.yml, change:
```yaml
permissions:
contents: read
pull-requests: write
issues: read
id-token: write
```
