[codex] finish effect fn checklist

[juliusmarminge]

Summary

• mark docs/effect-fn-checklist.md complete for the original checklist scope
• note that the follow-up exact () => Effect.gen(...) scan also migrated apps/server/src/terminal/Layers/Manager.ts

Why

• keep the migration checklist accurate after the remaining file work was split into one-file PRs
• document that the post-checklist scan for newly introduced exact-empty-arg wrappers came back clean after the final migration

Validation

• bun fmt
• bun lint
• exact scan: rg -n -U --multiline --glob '!*.test.ts' --glob '!docs/effect-fn-checklist.md' '\(\)\s*=>\s*\n\s*Effect\.gen\(function\*|\(\)\s*=>\s*Effect\.gen\(function\*' apps packages

Notes

• validation was run from the completed checklist scratch branch before splitting these per-file PRs
• bun run test and bun typecheck at the repo root currently fail in apps/web because @effect/atom-react cannot be resolved
• apps/server still has unrelated pre-existing typecheck failures outside this file

Note

Mark effect fn migration checklist as complete in docs

Updates effect-fn-checklist.md to reflect that all effect function migrations are done. Marks completed items across all major components (ClaudeAdapter, ProviderService, OrchestrationEngine, EventNdjsonLogger, CodexAdapter, CheckpointStore, cli.ts handlers, projector.ts, and the smaller clusters section), and adds a summary note about a follow-up migration task.
