Follow X user
Input
handle requiredX handle without the leading @ (e.g. 'jaminball'). The follow takes effect immediately (or a follow request is sent, for protected accounts) and is visible to the target account and to anyone viewing your following list, so confirm the exact handle with the user before running rather than inferring it from an earlier or unrelated message.
Output
handle requiredis_following requiredFollow-state read back after the action - true only once actually following; stays false for a pending request to a protected account, since X doesn't count that as following until they approve.
was_following requiredalready_present signal: true if already following, or a request was already pending, on arrival.
verified_on_page requiredtrue if the page was reloaded and re-inspected after the action, confirming the resulting state is actually visible/present
status optionalfollowed = the button flipped to Following/Unfollow after our click; already_following = it was already in that state; requested = the target account is protected/locked, so a follow request was sent (or one was already pending) instead of following immediately - is_following stays false until they approve it.
account_used optionalhandle of the logged-in account that performed the action, read from the account switcher UI (not assumed from input)
