Fix Zookeeper bulk edit stale project handling

[harsh181018]

Summary

• skip the bulk-delete project lookup when a Zookeeper/SystemIO bulk edit has no files to delete
• add a SystemIO file-system failure callback so pending Zookeeper history writes can be cancelled
• clear the Zookeeper history recording guard on bulk write failure so file watchers/re-exec do not stay suppressed

Testing

• ./node_modules/.bin/vitest run --mode=development --project=integration src/machines/systemIO/systemIOMachine.spec.ts
• ./node_modules/.bin/biome check --formatter-enabled=true --linter-enabled=false --organize-imports-enabled=true --files-ignore-unknown=true src/components/layout/areas/MlEphantConversationPaneWrapper.tsx src/machines/systemIO/systemIOMachine.spec.ts src/machines/systemIO/systemIOMachine.ts src/machines/systemIO/systemIOMachineImpl.ts

Notes

• npm run tsc still fails in this clean worktree because generated Rust binding files under @rust/kcl-lib/bindings are missing; grep of the tsc log showed no errors in the touched files.
