fix(ci): use custom dev versioning to preserve stable version coupling

Replaces semantic-release for dev branch with custom script that:
- Bases dev versions on current stable (e.g., 6.7.1-dev.N)
- Increments only the dev number, not the base version
- Keeps GitHub releases, issue tagging, Discord notifications
