`mcp__hyperhive__remind` calls previously rendered as the generic
`fmtArgsGeneric` output — with a multi-field input that showed
`message: "..." · delay_seconds: 300`, burying the message after
a verbose field name.
New format: `remind* +5m "check on PR..."` (or `at HH:MMZ` for
absolute timestamps). The timing renders first so it's scannable
at a glance, followed by the first 60 chars of the message body.
Works for all three input shapes: delay_seconds, at_unix_timestamp,
and file_path-only (shows the path as the preview).
