Easier invites: personal links and referral codes

2026-04-15 — v0.5.115

Share a personal invite link from the sidebar, manage a referral code in Settings, and let new users enter a code during onboarding to join you immediately.

What changed:

• Sidebar: added a Share option that generates your personal invite link for copy-and-paste.
• Settings: new referral-code controls so you can copy or reset your code anytime.
• Onboarding: new users can enter a referral code as they sign up so they join you on first use.

Why it matters: Inviting people now takes seconds. Fewer manual steps means new teammates land in the right place immediately, and you spend less time chasing sign-ups.
