fix(init): Include AGENTS guidance in non-interactive JSON

Capture AGENTS guidance outcomes during non-interactive init and embed the status in the emitted JSON report. Include path and error details when AGENTS updates fail so automation can reason about partial success without parsing stderr.

Preserve existing failure behavior by throwing after JSON emission on AGENTS errors, and extend init command tests to cover created, updated, and error statuses in JSON output.
