refactor: rename API and frontend projects to Vocero

Rename the project directories, Python distribution and import package, and npm package. Update launcher, Docker, tooling, tests, lockfiles, and documentation while preserving existing API contracts.

Make AGENTS.md self-contained and remove external skill and workflow references.
