v0.5.0 — contacts, docs create, own-calendar events

Three tools that finish the personal-assistant loop:

• contacts_search — names → email addresses across saved AND auto-collected contacts, so "draft an email to Mike" can find Mike.
• docs_create — a NEW private Google Doc with initial text. Create-only: existing docs are never edited.
• calendar_create_event — timed or all-day events on your own calendar. Takes no attendees — inviting people emails them, and this plugin never sends.

⚠️ Needs a reconnect: these use new scopes (contacts.readonly, contacts.other.readonly, documents, now in the connect defaults). Tokens minted earlier keep working for everything else and return a readable insufficient-scope error on the new tools until you hit Reconnect in the Google panel.
