Restore google/go-cmp in go.mod to reduce PR #710 merge conflicts with dev

[Copilot]

PR #710 (copilot/refactor-chat-feature → dev) has merge conflicts after dev merged PR #705 (internal tools). The previous conflict resolution attempt edited files to the correct state but didn't perform an actual git merge, leaving git-level conflicts unresolved.

Changes

• go.mod: Restored github.com/google/go-cmp v0.7.0 // indirect — present in both merge base and dev, accidentally dropped when PR feat(chat): add langchaingo agent execution path for chat module #710 added langchaingo deps. Eliminates this line as a conflict source in the second require block.

Remaining manual resolution needed

The structural conflict in chat/chat.go cannot be resolved without git merge dev. Dev added internal tools inline in Chat(), while PR #710 split it into chatWithAgent()/chatWithLegacy(). The PR branch already incorporates dev's changes within chatWithLegacy() — when merging, accept the PR branch's version of chat/chat.go.

File	Description
go.mod	Restores google/go-cmp indirect require to eliminate a known merge-conflict hotspot.
chat/agent_test.go	Updates the streaming callback test to use t.Context() and adjusts formatting around fakeTool methods.

[Copilot]

The extra spacing used to align the { in these method declarations is not gofmt-formatted and will be rewritten by gofmt (and may fail CI if formatting is enforced). Please run gofmt / remove the alignment spaces so the declarations match standard Go formatting.
