pub fn apply_config_migration_fixes(root: &Path) -> Result<bool>Expand description
Rewrites .apm/config.toml (or apm.toml) to migrate legacy worker config
fields to the current worker_profile = "agent/role" shape.
Handles two generations of legacy format:
- V1→V2:
[workers] command/args/model→[workers] agent/options.model - V2→V3:
[workers] agent/options.model→[workers] default/model
Returns true when the file was rewritten, false when no migration was needed
or migration was blocked by a non-Claude command.
