[codex] print validator count to stdout

[MuncleUscles]

Summary

• print localnet validators count results to stdout
• keep the existing spinner success message

Why

The Studio tooling E2E expects a parseable validator count. The CLI previously only surfaced the count through spinner output, which can be blank or suppressed in CI.

Validation

• npm test -- tests/actions/validators.test.ts
• focused Studio CLI validator count E2E locally

Summary by CodeRabbit

• Chores
  • Enhanced console output for validator count reporting in localnet operations.
  • Code formatting improvements.

Poem

A logger's gift, so small and bright,
Counts validators, outputs light,
Console whispers "All is well,"
No trailing blanks—the tale we tell. 🐰✨
