- Create src/models-resolver.ts with resolveModelsJsonPath() function - Fallback chain: ~/.gsd/agent/models.json → ~/.pi/agent/models.json → create new - Integrate into cli.ts ModelRegistry initialization - Provides smooth migration path for users with existing pi-coding-agent config

* Models.json resolution with fallback to ~/.pi/agent/models.json

* GSD uses ~/.gsd/agent/models.json, but for a smooth migration/development
|
|
* experience, this module provides resolution logic that:
|
|
*
|
|
* 1. Reads ~/.gsd/agent/models.json if it exists
|
|
* 2. Falls back to ~/.pi/agent/models.json if GSD file doesn't exist
|
|
* 3. Merges both files if both exist (GSD takes precedence)
