Checks if an action has transpilable client-side operations (sets/updates).

Actions with effects, submits, navigates, or invokes can still be partially optimistic — the sets run client-side immediately while the server handles the side effects.

Analyze a value to determine how to generate JS for it.

Returns:

• {:rx, source} for rx() expressions
• {:literal, value} for simple literals
• :from_params_value for param accessors
• :unknown for non-transpilable values

Normalize a dependency to its root field name as a string.

Path deps like {:path, :params, ["name"]} become "params". Atom deps like :count become "count".
