v0.8.4 Release - TConfig Generic Support in CLI

Minor release adding TConfig generic parameter to createCLI for type-safe custom configuration types.

Feature

#152: TConfig Generic Parameter in createCLI

• Added TConfig generic to CLIOptions and createCLI interfaces
• extendFlags and createExecutor callbacks now receive typed config
• Full IntelliSense support for custom config properties
• No type casting needed for adapter-specific configs

Impact

Firebase Team Unblocked:

• Can use createCLI<IFirebaseDB, FirebaseAdapter, FirebaseConfig>() with full type safety
• extendFlags callback receives FirebaseConfig type (not base Config)
• createExecutor callback receives FirebaseConfig type (not base Config)

Type Safety Completion:

• Completes type safety story from v0.8.0-v0.8.3
• Consistent with THandler (#138) and executor TConfig (#144)
• Same pattern across all generic type parameters

Quality Metrics

• Tests: 1572 passing (+4 new tests for TConfig support)
• Coverage: 100% maintained (2815/1450/581/2713)
• Backward Compatibility: ✅ Default TConfig = Config preserves existing behavior
• Documentation: Updated cli-adapter-development.md with Firebase examples
• Effort: ~10 minutes implementation (as estimated)

Related Issues

• #138: Added THandler generic for type-safe handler access
• #144: Added TConfig generic to executor interfaces
• #151: Added addCustomOptions/extendFlags callbacks (v0.8.3)

Migration

No breaking changes - fully backward compatible. Existing code works without modifications.

Optional Enhancement:

// Before (works but requires casting)
createCLI({ ... })

// After (optional type safety)
createCLI<IDB, Adapter, CustomConfig>({ ... })
