Subject: [PATCH] scaffold generated CLI integration point in main.rs

openapi-transformer will regenerate pup CLI command modules from the
OpenAPI spec into src/generated.rs (see DataDog/pup#651, the pilot run
for this pipeline). Land the wiring ahead of that so main.rs never needs
touching again on future regenerations: mod generated, flatten
GeneratedCommand into the Commands enum so generated subcommands appear
as top-level peers, and route the arm through main_inner() following the
existing per-domain pattern.

src/generated.rs here is a placeholder with an empty GeneratedCommand
enum, not #651's actual generated output - #651 hand-writes a top-level
downtime command (list/get/create/cancel) that collides on the
subcommand name with the generated Downtime variant it introduces
(clap panics at runtime: "command name `downtime` is duplicated"). That
collision needs a product decision - retire/merge the hand-written
downtime command, or pick a different pilot operation upstream - before
any generated variants land. This PR only establishes the scaffold; #651
becomes a pure additive diff to generated.rs (and new sibling modules)
once that decision is made.
