Builds on top of https://github.com/coder/coder/pull/16623/ and wires up the ReconnectingPTY server. This does nothing to wire up the web terminal yet but the added test demonstrates the functionality working. Other changes: * Refactors and moves the `SystemEnvInfo` interface to the `agent/usershell` package to address follow-up from https://github.com/coder/coder/pull/16623#discussion_r1967580249 * Marks `usershellinfo.Get` as deprecated. Consumers should use the `EnvInfoer` interface instead. --------- Co-authored-by: Mathias Fredriksson <mafredri@gmail.com> Co-authored-by: Danny Kopping <danny@coder.com>
