chore: remove bootstrap scripts from main

The tools/seed-gitea.sh seeder + README reached main via an earlier chore

they seeded already exists in Gitea.

-**Outcome:** A fresh `git clone` from the Respellion Gitea remote, followed by `docker compose up`, produces a green "hello world" health endpoint from a placeholder BFF. Gitea Actions runs lint, build, unit tests, and the compose-up smoke test, all green. Issue templates, PR template, milestones, labels, and the first project board exist in Gitea.
