Add commands to manage pipeline elements (pre-scripts, transforms,
post-scripts, source, destination) matching the UI functionality:
- prescript/postscript: add, remove, edit, move-up, move-down
- transform: add, remove, edit, move-up, move-down with type shortcuts
- source: edit (connection, query, mass-query)
- destination: edit (table, match columns, exclude from update)
Features include 1-based indices, --dry-run support, file input for
scripts/queries, and numbered element display in pipeline show output.
