Add option to use skills in custom agent base on deepagents (non-cli version)

[oleg-savko]

Its will be very helpfull and interesting try to use skills in deepagents package (non-cli version) in custom writing agent on it.

For common use cases cli version not appropriate, and need something like chat base application to interact with custom agent (with skill support, it will be interesting to investigate results)
