Fix QUICKSTART.md with foundation approach - tea CLI just works

Added one-time setup:
- Export GITEA_TOKEN
- tea login add

This is THE foundation for agent workflow. Without this, agents can't:
- Query their tasks programmatically
- Create PRs
- Participate in the Git workflow

Updated workflow section:
- Use tea CLI for task list and PR creation
- No scripts needed
- No asking permission
- Commit with 'Fixes #N', push, create PR, wait for review

Added building section:
- Standard vs commercial (-tags commercial)
- Test before committing

Now Hans can:
1. tea issues list --assignees hans (see tasks)
2. Fix code
3. tea pulls create (submit for review)

Foundation: tea CLI works.
