Subject: [PATCH] feat: support the code_channels manifest feature

Add the code_channels feature block to the manifest types so the CLI can
read, write, and round-trip it (enabled, optional slash_command_url).
Follows the existing feature-block pattern; validation is handled by the
manifest validation endpoint.
