docs(effect-ts): skip prepare setup in CI

[altaywtf]

Summary

Update the Effect source setup guide so the local clone prepare helper exits when CI=true. This keeps the current local setup ergonomics while avoiding unexpected .repos/effect clones in CI/CD automation workspaces.

Changed

• Document that option 3 bootstraps the clone only outside CI.
• Add the CI=true guard to the concrete scripts/prepare-effect.sh shape.
• Note that install, pack, publish, or CI/CD flows should not clone .repos/effect when running under CI.

Risks

Low. This is documentation-only, but it changes the recommended script shape for option 3.

Verification

• git diff --check

Complexity

Reduced: keeps local automatic setup while avoiding CI/CD side effects.

Pull request overview

Updates the Effect source setup documentation to avoid using package-manager lifecycle hooks (e.g., prepare) for cloning the local Effect repo, replacing it with an explicit setup:effect task to prevent unintended clones during install/CI/pack/publish flows.

Changes:

• Renames the “local clone” option to use an explicit setup task rather than a prepare lifecycle script.
• Replaces the example prepare script entry with setup:effect and updates the referenced shell script name accordingly.
• Adds explicit guidance warning against wiring this helper to lifecycle hooks like prepare/postinstall.
