Cherry-pick investigation: PR #14791 already applied to dev

[Copilot]

PR #14791 fixed a file name reference bug (teamsapp.yaml → m365agents.yaml) in packages/vscode-extension/package.nls.json. Investigation confirms this change is already present in the dev branch.

Findings

• Verified line 638 in both branches contains identical fix: m365agents.yaml and m365agents.local.yaml
• Change likely applied during previous rebranding merge
• No cherry-pick action required

File Comparison

# Both branches at line 638:
"teamstoolkit.handeler.addAuthConfig.notification": "Microsoft 365 Agents Toolkit has successfully updated your project configuration (m365agents.yaml and m365agents.local.yaml) files..."

Dev branch has one additional unrelated line (651) for MCP error handling, which is expected.
