chore: sync submodules + remove tracked secret files

[POWERFULMOVES]

Summary

• Sync 8 submodule pointers to latest upstream commits: Archon, BoTZ, Danger-infra, Headscale, Open-Notebook, Pipecat, ToKenism-Multi, tensorzero
• Remove root-level env.tier-* files — these contained plaintext secrets (PRESIGN_SHARED_SECRET, POSTGRES_PASSWORD, MINIO_ROOT_PASSWORD, API keys) that should NOT be in version control. Canonical env files live in pmoves/ folder (already gitignored).
• Update .gitignore to prevent env.tier-* from being re-tracked

Test plan

• Verify submodule pointers resolve to valid commits
• Confirm env.tier-* files are no longer tracked
• Confirm pmoves/env.shared or .env.local still contains required secrets for deployment
• Run make verify-all smoke tests
