Module deploy_adapter 

Deploy adapter trait + per-target stubs for the ssg deploy subcommand (issue #527 AC4).

The legacy crate::deploy::DeployPlugin generates platform-specific configuration files (netlify.toml, vercel.json, …) at build time. This module is responsible for the upload half — taking a freshly built site_dir and shipping it to the target platform.

Each adapter is a stub at the moment: it prints "deploy adapter for <target>: not yet implemented; see #527" to stderr and exits cleanly. The wiring and CLI surface are in place so we can land the rest of the implementation behind it without breaking the ssg deploy --target … API.

Stability

Target is #[non_exhaustive] — new targets can be added in minor releases. Downstream match arms must include a wildcard.
