chore(release): 0.61.1

[fnnzzz]

Summary

• Bumps the version to publish bc49f99 (fix(dispatch): refuse a prompt too large for the seat's known TPM ceiling #107, fix(dispatch): refuse a prompt too large for the seat's known TPM ceiling), which merged after 0.61.0 was already cut and has been sitting unreleased.
• The 0.61.0 npm build still lets a direct dispatch call bypass pick's TPM-ceiling check, so it keeps hitting the 413s that fix(dispatch): refuse a prompt too large for the seat's known TPM ceiling #107 was written to fix (confirmed against groq-gpt-oss-120b/-2 and groq-qwen3.6-27b failures from the last 24h).
• No other changes bundled — this is release-only.

Test plan

• git diff reviewed: only package.json version and CHANGELOG.md entry changed
• CI gates pass on this PR
• Merge triggers the auto-publish-on-version-bump release workflow (ci(release), ci(release): auto-publish to npm on a version bump, with manual dispatch as a fallback #103) and npm serves 0.61.1
