Description

Adds a one-line if guard to the Release Please job in the main workflow to prevent an infinite loop. When release-please merges its own PR, the resulting chore(main): release commit triggers the workflow again, which runs release-please again, creating an endless cycle. The guard skips the Release Please job when the triggering commit message starts with chore(main): release.

• Add if condition to Release Please job in .github/workflows/main.yml to skip bot commits
• Update docs/architecture/workflows.md with Mermaid highlight, explanatory paragraph, and table revision

Security Considerations

• This PR does not contain any sensitive or NDA information
• Any new dependencies have been reviewed for security issues
• Security-related scripts follow the principle of least privilege

Additional Notes

• The if expression requires double-quoting in YAML because the commit prefix chore(main): release contains a colon character
• The expression uses ${{ !startsWith(...) }} to ensure correct evaluation in GitHub Actions
• Milestone: v2.3.0 (due 2026-02-11)
