feat: add deploy command and deploy-after-upload support

[lee-reinhardt]

Summary

Adds avocado connect deploy for deploying runtimes to cohorts, and --deploy-* flags on avocado connect upload for one-command upload+deploy workflows.

New: avocado connect deploy

Standalone command to create a deployment targeting a cohort with a runtime.

• Interactive runtime and cohort pickers when flags aren't provided (auto-selects when only one option exists)
• --runtime <id> and --cohort <id> for non-interactive use (validated against the project)
• --name <name> for deployment name (auto-generated from runtime version + timestamp if omitted)
• --description <text> for optional description
• --tag / -t (repeatable) to filter deployment to devices with matching tags
• --activate to skip draft and immediately activate the deployment
• Deployment ID is always printed before activation is attempted, so it's never lost if activation fails

# Interactive
avocado connect deploy

# Non-interactive
avocado connect deploy --runtime <id> --cohort <id> --activate

# With tag filtering
avocado connect deploy --runtime <id> --cohort <id> -t production -t us-west --activate

New: upload --deploy-* flags

Upload and deploy in one command. After a successful upload, automatically creates a deployment using the freshly uploaded runtime.

• --deploy-cohort <id> — required to trigger deploy-after-upload
• --deploy-name <name> — optional deployment name
• --deploy-tag <tag> — optional tag filter (repeatable)
• --deploy-activate — activate immediately

Using --deploy-name, --deploy-tag, or --deploy-activate without --deploy-cohort raises an explicit error.

avocado connect upload dev --deploy-cohort <id> --deploy-activate
