fix: Remove dead release.yml workflow

[dean0x]

Problem

.github/workflows/release.yml is a dead workflow that fails on every run because it calls npm test, which exits with code 1 (the technical safeguard that prevents full test suite runs). The ci.yml release job already handles npm publishing on push to main, making release.yml redundant and confusing.

Scope

1. Delete .github/workflows/release.yml
2. Verify ci.yml release job is the sole publish mechanism
3. Confirm CI passes end-to-end after deletion

Acceptance Criteria

• release.yml no longer exists in the repo
• ci.yml release job publishes successfully on push to main
• No duplicate workflow runs on merge to main

Dependencies

• Depends on NPM_TOKEN rotation issue (need valid token to verify CI end-to-end)
