Add or remove a company from the user's watchlist. This changes saved preferences, not financial assets. Only remove deletes an entry.
action='add' and action='remove' each take one symbol and are idempotent: adding a company already on the list leaves it there, removing one that is not on the list is a no-op. Both report the resulting list size.
Not this tool for: holdings and cash (that is a portfolio — use get_portfolio / import_portfolio), or for any market data. The watchlist stores which companies the user follows, nothing about quantities, prices or returns.
