Refactor: Consolidate to single unified deployment job

Replaced two separate deployment jobs with one unified job that detects
the branch and deploys accordingly. This completely eliminates the
concurrency/cancellation issues.

Changes:
- Single 'deploy' job replaces 'deploy-develop' and 'deploy-main'
- Uses conditional steps with 'if: github.ref_name == ...' checks
- Uses conditional parameters in peaceiris action:
  - destination_dir: develop branch → 'development', main → '.'
  - keep_files: develop branch → true, main → false

How it works:
- Develop: Deploys to /development/ with keep_files, skips preservation
- Main: Preserves /development/, deploys to root, restores /development/

Benefits:
- No more concurrency conflicts (only one deployment per workflow)
- Simpler, more maintainable code
- Same end result with less complexity
