Improve simulator limit errors and fix telemetr

[ejacquier]

Summary

Improves simulator limit error handling to be more actionable and ensures CLI telemetry captures all simulation failures.

Changes

• New LimitExceededError type (limit_errors.go): Introduces a typed error for simulation limit violations, allowing callers to distinguish limit-exceeded failures via
  errors.As() without string matching.
• Enhanced limit error messages: All limit-exceeded errors now include:
  • Clear indication of actual vs. limit values
  • Production context (whether the limit mirrors a production constraint)
  • Actionable remediation hints (cre workflow limits export or --limits=none)
• Fixed telemetry bypass: Replaced os.Exit(1) in simulation hooks with proper error returns so the CLI telemetry system captures all failures and propagates
  ExecutionResult_Error as non-zero exit codes.
• Improved test coverage: Added comprehensive tests for limit error generation and simulation error handling paths.

Why this matters

• Better UX: Users get clear, actionable guidance when hitting limits instead of cryptic errors
• Observability: All simulation failures now properly reported through CLI telemetry
