feat: goose: add support for subdomain=false (#299)

Updates https://github.com/coder/coder/issues/18779
Builds on https://github.com/coder/registry/pull/297

## Description

Adds support for specifying `subdomain = false` in the agentapi module.
Change added in https://github.com/coder/registry/pull/297
NOTE: `AGENTAPI_CHAT_BASE_PATH` is exported before running `main.sh` in
agentapi, so this environment variable is available to calling modules
if `var.subdomain = false`.

- [X] Feature/enhancement
- [ ] Documentation
- [ ] Other
