Review: Release 1.661.0

• Review changed files
• Provide feedback

This is an automated Release Please PR. The changes are minimal and correct:

1. CHANGELOG.md — Adds the 1.661.0 section with the single feature entry for OTel metrics support (#8442). Formatting and links are correct.
2. version.txt — Bumps version from 1.660.1 to 1.661.0. Correct semver minor bump for a new feature.

No issues found. LGTM.

---

Testing instructions: This is a version bump and changelog update only — no functional changes to verify through the app. The OTel metrics feature itself was merged in #8442 and should be tested separately.
