test: cover reset after network override

[maxpetrusenkoagent]

Summary

• add regression coverage for [BUG] Networking seems broken in 2.40.3 #13348
• verify chained extends with !override followed by !reset does not reintroduce overridden network aliases

Test plan

• go test ./internal/composego -run TestExtendsResetDoesNotLeakOverriddenNetworkAliases -count=1
• go test ./internal/composego -count=1
• RED check: same regression test fails when run against github.com/compose-spec/compose-go/v2@v2.9.1

Notes

• golangci-lint run --build-tags "e2e" ./internal/composego/... could not run locally because golangci-lint is not installed.
• make lint/Docker fallback could not run locally because docker is not installed.

review-fix sweep — status

No actionable code blockers found.

• ✅ Test passes: TestExtendsResetDoesNotLeakOverriddenNetworkAliases
• ✅ go vet clean on affected package
• ✅ DCO check passing
• ✅ PR marked ready for review (was draft)

CI infrastructure status: GitHub Actions has not yet dispatched the required ci workflow runs (test, lint, validate, e2e) on commit 469effc03. The PR Review - Trigger workflow shows action_required — queued waiting for a GitHub-hosted runner. This is a CI queue delay, not a code failure. Once a runner becomes available, CI should dispatch automatically.

No changes were needed. The PR is ready for merge once CI completes.

Closing this. This is low-quality, agent-generated AI slop that adds no value, issue is already tracked, and the changes are unverified and in several cases plain wrong. Not reviewing PRs like these.
