Fix Gauntlet Provider Validation Logic

• Fix Gauntlet Provider Validation Logic
  • Identified issue where gauntlet command was checking current provider instead of requested provider
  • Analyzed that the early check in handleGauntletCommand was blocking valid gauntlet executions
  • Removed incorrect check for this.currentLLMProvider === 'copilot' since gauntlet creates its own bot instance
  • Verified that existing argument parsing already prevents copilot from being specified as --provider
  • Updated tests to reflect corrected behavior - gauntlet can run regardless of current provider
  • Added test coverage for edge cases: openai provider when current is copilot, and blocking explicit copilot requests
  • Validated fix ensures gauntlet works with any valid provider (openai/ollama) regardless of bot’s current state
