chore: bump version to 0.0.61

[CarmenDou]

What

Bumps the version to 0.0.61 so the GitHub URL template target can ship.

How

package.json and package-lock.json only, the same two files as the 0.0.60 bump (#181). The
lockfile was regenerated with npm install --package-lock-only rather than hand-edited.

Released by this version: insta template deploy <github-url> (#183), which fetches
insta.template.yaml from a GitHub repository on the user's own machine, with the user's own git
credentials, and deploys it through the existing inline-manifest pipeline. Its agent-facing
documentation landed alongside in insta-skills#76.

Verify

npm run typecheck && npm test

After merge, v0.0.61 gets tagged and the release workflow publishes the five platform binaries
and the npm package. Confirm with npm view insta version and the GitHub Release page.
