- Fix SSH action workflows: replace deprecated script_stop with set -e

[Copilot]

Since appleboy/ssh-action v1.2.2, the script_stop parameter is no longer supported and causes workflow failures. The equivalent behavior is achieved by adding set -e at the top of the script block.

Changes

• Removed script_stop: true from all three affected workflows
• Added set -e as the first line of each script block

Affected workflows: run-command-on-beta.yml, deploy-to-beta-manually.yml, deploy-to-prod.yml

# Before
script_stop: true
script: |
  cd /app && make deploy

# After
script: |
  set -e
  cd /app && make deploy
