Send recognition (a bonus) to one or more colleagues on behalf of the
authenticated caller. Inputs: one or more recipients, an integer points
amount, a free-form reason, and one company hashtag.

Inputs:

• recipients (array of strings) — each entry is a user id, email address,
  or display name.
• amount (integer) — points to give. Pass 0 only if your company allows zero-point.
• reason (string) — free-form recognition message (no need to include @mentions or
  +amount — they're synthesized from recipients and amount).
• hashtag (string) — one company hashtag without the leading # (e.g. "teamwork").

When any required input is missing or a recipient cannot be resolved, the response
either carries a requestedSchema (for clients that declared elicitation at
initialize) or a standard INVALID_PARAMS error.

Returns the new bonus id and a permalink path on success.
