Walkthrough

The PR upgrades Go toolchain and multiple dependencies (notably github.com/conductorone/baton-sdk), removes redundant blank imports across connector files, updates resource call sites to use sdkResources, and changes a CreateAccount parameter type and adds a static interface assertion in server_user.go.

Changes

Cohort / File(s)	Summary
Dependency & Toolchain Updates go.mod	Go toolchain upgraded from 1.24.1 to 1.25.2; github.com/conductorone/baton-sdk bumped v0.2.99 → v0.7.4; github.com/stretchr/testify bumped v1.10.0 → v1.11.1; several indirect dependencies added/updated (e.g., semver/v3, purego, otter v2, gopsutil v4, golang.org/x/sys v0.38.0).
Redundant Import Removal pkg/connector/connector.go, pkg/connector/database.go, pkg/connector/group.go, pkg/connector/server.go, pkg/connector/server_role.go, pkg/connector/server_user.go	Removed duplicate/blank underscore imports of github.com/conductorone/baton-sdk/pkg/annotations, consolidating to a single named import where applicable.
SDK Resource Reference Migration pkg/connector/database_role.go	Replaced resource.NewRoleResource → sdkResources.NewRoleResource and resource.WithParentResourceID → sdkResources.WithParentResourceID; removed now-unused local resource imports.
Server user API & Static Assertion pkg/connector/server_user.go	Added static type assertion: var _ connectorbuilder.AccountManagerLimited = (*userPrincipalSyncer)(nil); changed CreateAccount parameter type from *v2.CredentialOptions to *v2.LocalCredentialOptions.

Poem

🐇 I hopped through modules, versions took flight,
I nudged blank imports out of sight,
Swapped resource names with a tidy cheer,
Adjusted a sig and left a type near,
A little rabbit’s patch—clean and light.
