Fix tool install-state, inherit program description, declutter Tools cards

- Tool detail showed installed tools as 'Not installed': /deployments/{name}
  populated 'installed' for path deployments but left 'active' null, and
  ToolDetail keyed off 'active'. Now the endpoint sets active=installed for path,
  and ToolDetail reads 'installed' directly (verified: on-PATH ⇒ True, else False).
- A deployment now inherits its program's description by default: copied at
  creation (CLI create + API _save_deployment on new deployments) + a one-time
  patchup of existing ones (29 deployments).
- Tools page cards no longer list deployments (ProgramCard showDeployments=false) —
  the lens already scopes to the tool; the deployment list is a Programs-catalog thing.
