When no provider field is set but model is specified, use the user's model
as ModelName for the first provider. This maintains backward compatibility
with old configs that relied on implicit provider selection and ensures
GetModelConfig(model) can find the model by its configured name.
- Preserve user's configured model during config migration (issue #5)
- Simplify ExtractProtocol using strings.Cut
- Extract NormalizeToolCall to shared utility, removing ~70 lines of duplicate code
- Clean up unused fields in providerMigrationConfig struct

Refactor command handlers into separate files to improve code organization
and maintainability. Each command (agent, auth, cron, gateway, migrate,
onboard, skills, status) now has its own dedicated file.
Restructure provider creation to support new model_list configuration
system that enables zero-code addition of OpenAI-compatible providers.
Move legacy provider logic to separate file for backward compatibility.
Move configuration functions from config.go to separate files
(defaults.go, migration.go) for better organization.
