chore(release): 1.8.1

[socket-release-bot]

Bumps package.json to 1.8.1 and moves the ## [Unreleased] notes under the 1.8.1 heading.

To release:

1. Review the CHANGELOG section and squash-merge this PR.
2. Dispatch Publish to npm registry on v1.x with dry-run: false. It tags the merge commit, cuts the GitHub release, and stages all three packages.
3. Approve each staged package with pnpm stage approve.

If v1.x moves before this merges, re-dispatch with mode: release-pr to rebuild the bump on the new tip.

Note

Low Risk
Version and changelog-only release bump with no runtime code changes in the diff.

Overview
Prepares socket CLI v1.8.1 for release by bumping package.json from 1.8.0 to 1.8.1 and promoting the former ## [Unreleased] changelog section to a dated 1.8.1 entry (2026-10-12), documenting the Coana CLI update to 15.12.7.

No application code changes in this diff—only version and release notes metadata.
