Start a local Temps server

Boots the temps binary from source (cargo run --bin temps --package temps-cli -- serve ...) for quick local iteration, no debugger required. See CONTRIBUTING.md for the one-shot manual version of this; this skill adds port isolation across worktrees and a repeatable restart flow.

Prerequisites

• The database container from CONTRIBUTING.md ("Database" section) running and reachable, e.g.:

  docker run -d --name temps-db --restart unless-stopped \
    -p 127.0.0.1:5432:5432 \
    -v temps-db-data:/home/postgres/pgdata/data \
    -e POSTGRES_USER=temps -e POSTGRES_PASSWORD=temps -e POSTGRES_DB=temps \
