refactor: rename tli→fxt, delete legacy scripts/RunPod/deploy artifacts

- Rename tli/ directory to fxt/, update package + binary name to "fxt"
- Replace all `use tli::` → `use fxt::` across 52 Rust files
- Update build.rs proto paths (tli/proto → fxt/proto) in 6 services
- Update Dockerfiles, CI workflows, deploy.sh for new paths
- Delete ~170 legacy shell scripts (kept 15 essential ones)
- Delete RunPod Python client (runpod/), tests (tests/runpod/)
- Delete foxhunt-deploy crate (RunPod-only deployment tool)
- Delete terraform/runpod/ (moved to Scaleway)
- Delete ML Python hyperopt scripts (replaced by Rust Argmin PSO)
- Delete .gitlab-ci.yml (using GitHub + Gitea)
- Remove foxhunt-deploy from workspace members

504 files changed, -74,355 lines of legacy code removed.
