feat(ipuaro): add error handling matrix and ErrorHandler service

Implemented comprehensive error handling system according to v0.16.0 roadmap:

- ERROR_MATRIX with 9 error types (redis, parse, llm, file, command, conflict, validation, timeout, unknown)
- Enhanced IpuaroError with options, defaultOption, context properties
- New methods: getMeta(), hasOption(), toDisplayString()
- ErrorHandler service with handle(), wrap(), withRetry() methods
- Utility functions: getErrorOptions(), isRecoverableError(), toIpuaroError()
- 59 new tests (27 for IpuaroError, 32 for ErrorHandler)
- Coverage maintained at 97.59%

Breaking changes:
- IpuaroError constructor signature changed to (type, message, options?)
- ErrorChoice deprecated in favor of ErrorOption
