LLVM 22 cloud VM bootstrap + Studio vertical tick hooks

Summary

Cloud Agent VMs install LLVM 22 via scripts/cloud-vm-bootstrap.sh, and all seven Studio sim profiles call domain *_tick_stub hooks from studio_sim_step_hook.

Agent continuation

  1. Read: docs/ecosystem/cloud-agent-vm.md, docs/game-dev/studio-full-implementation-plan.md §1.2.
  2. Run: bash scripts/cloud-vm-bootstrap.sh; lic check packages/li-studio/li-tests/smoke/studio_sim_step_by_profile.li.
  3. Next: Deepen each vertical (IK, printer export, LITL stages, RL env pool) on cursor/vertical-*-5599 branches.
  4. Blocked: Wave A lic build Lean gate — domain kernels remain stub-level.

Changed

  • scripts/cloud-vm-bootstrap.sh — LLVM 22, env file, lic build
  • docs/ecosystem/cloud-agent-vm.md, docs/guide/devbox-li-development.md, AGENTS.md
  • packages/li-sim-{robotics,automotive,additive,drug-design}/src/lib.li — *_tick_stub / *_tick_at
  • packages/li-sim/src/lib.li — sim_rl_tick_stub
  • packages/li-studio/src/lib.li — studio_sim_step_hook dispatches all sim profiles
  • Smokes: tick_stub.li per domain pack; extended studio_sim_step_by_profile.li

Not changed

  • Compiler Wave A (2e/2f/7e), wgpu viewport, lis mcp li-engine, benchmarks verticals.toml ingest.

Breaking

N/A — install script path change only for Cloud VMs using the old LLVM 18 inline cmake line.

Security

N/A — toolchain bootstrap only.

Performance

N/A — stub ticks; no bench threshold changes.

Downstream

Point Cursor Cloud install script at bash /agent/repos/lic/scripts/cloud-vm-bootstrap.sh.
