fix(memory): use --id for memory selectors

[notgitika]

This PR standardize the parent Memory selector on --id across event, record, actor, and session commands. We see this convention in the rest of the CLI.

I also add a regression assertion that imperative Memory selectors do not use --memory

bun build, typecheck, lint, format and test pass
