Move CI workflows to repo root .gitea/workflows/ (Gitea requires root location)

- 6 per-product CI workflows with path filters
- P1: Rust (cargo test + clippy + fmt)
- P2: Go agent (go test + vet) + Node SaaS (tsc + npm test)
- P3-P6: Node (npm ci + tsc + npm test)
- Removed old per-product .gitea dirs (Gitea ignores non-root workflows)
