fix(cli): dry run prints one honest list, and the real run admits routes

[bpamiri]

wheels generate scaffold Post … --dry-run printed three contradicting things at once:

Dry run — nothing will be written.
Scaffolding Post...
  create  model: Post.cfc            <- reads as "written"
  … ten create lines …
Scaffold complete! Next steps:
  1. Run migrations: wheels migrate latest   <- migrate what?
Would create:
  /private/tmp/dr/app/app/models/Post.cfc    <- absolute, root repeated

Nothing was written (that part was correct), but the output said otherwise and the trailing advice was nonsense for a dry run.

Fix

printCreated() is the single choke point for all 30 generator call sites, so gating it on $isDryRun() fixes every generator at once — model, controller, migration and scaffold alike. The scaffold's modify lines and the "Next steps" block are gated the same way.

The list is headed Would write:, not Would create:, because it legitimately contains paths that would be modified — a --belongsTo scaffold rewrites the parent model, controller and show view. Paths are now project-relative.

Dry run — nothing will be written.
Scaffolding Post...
Would write:
  app/models/Post.cfc
  app/migrator/migrations/2026…_create_posts_table.cfc
  app/controllers/Posts.cfc
  app/views/posts/{index,show,new,edit,_form}.cfm
  tests/specs/models/PostSpec.cfc
  tests/specs/controllers/PostsControllerSpec.cfc
  config/routes.cfm

The inversion the dry run exposed

The dry run listed config/routes.cfm while the real run rewrote that file without a word. updateRoutes() has always returned whether it changed the file; the caller discarded the value.

Scaffold now records it in results.routes — deliberately not results.modified, because config/routes.cfm is a shared project file rather than a per-model artifact, and the 17 parent-wiring specs assert the exact contents of modified. Module.cfc reports it as modify routes: config/routes.cfm.

Verified

dry run	11 project-relative paths, nothing written
real run	the same 10 creates + modify routes: config/routes.cfm
--belongsTo dry run	parent files in the would-write list, left byte-unchanged
model / controller / migration	clean single lists, no duplicates

CLI suite: 1375 pass, 0 error. The 4 remaining DbCommandSpec failures are environmental — they expect Wheels.ServerNotRunning and a live app was on 8080; on a clean port they pass.
