feat: add /pr-comms skill — public relations and crisis comms

[HMAKT99]

Crisis at 2am. You need a statement in 30 minutes.

Every minute of silence is filled by speculation. You need a holding statement NOW, a detailed response in an hour, and a post-mortem by end of week. Or: product launch tomorrow, no press strategy, no journalist contacts.

What /pr-comms does

You:   /pr-comms --crisis "User data exposed via API endpoint"
