ci: update Go version to 1.25 in GitHub Actions workflows

Update Go version from 1.24 to 1.25 across all build configurations:
- GitHub Actions workflows (test.yml, release-binaries.yml)
- Dockerfiles (deploy/Dockerfile, deploy/canary/Dockerfile)
- Build scripts (integration-in-docker.sh, unit-in-container.sh)
- Makefile docker-build target
- cmd/go.mod toolchain directive

Also update golangci-lint from v1.64.5 to v2.6.2 for Go 1.25 compatibility,
and migrate .golangci.yml to v2 format with appropriate exclusions for
pre-existing code style issues.
