chore: bump version to 0.0.67

[CarmenDou]

What

Bump insta to 0.0.67 so the next tag ships #206 (insta domain) and #210 (MCP token registration failures are reported and exit non-zero).

How

npm version 0.0.67 --no-git-tag-version, which touches only the version fields in package.json and package-lock.json.

Verify

• Diff is the two version fields and nothing else.
• After merge: tag v0.0.67 on main. The release workflow publishes the five binaries and the npm package. Check with npm view insta version.
