fix: add org baseline secret patterns to .gitignore

[don-petry]

Summary

• Copies the petry-projects org baseline .gitignore (secrets-only) verbatim into the repo
• Adds the missing *.pem and *.key patterns required by the push-protection standard
• Preserves existing repo-specific entries (node_modules/, coverage/, test-results/, playwright-report/) in a dedicated section at the top
• Removes the standalone .env entry (it's covered by the baseline's dotenv section)

Closes #172

Self-review

Change: Only .gitignore is modified — no code changes.

What was done:

• Preserved existing repo-specific entries (node_modules/, coverage/, test-results/, playwright-report/) in a dedicated section at the top
• Removed the standalone .env entry (it's now covered by the org baseline's dotenv section)
• Appended the full petry-projects org baseline verbatim, which includes the required *.pem and *.key patterns (section 4 — SSH / TLS / GPG key material)

No issues found — the change is a straight copy of the org baseline with repo-specific entries preserved. No logic, tests, or lint checks are affected.
