SDKs published; typed list responses

SDKs: @talkif/sdk 0.1.1 (npm) and talkif 0.1.1 (PyPI) are published. Both auto-page list endpoints and expose typed errors — see SDKs.
API: list endpoints now return typed responses (calls, contacts, campaigns, … plus meta) instead of untyped arrays; offset pagination starts at 0.
Calls: the call list is now GET /calls (replacing /calls/history and /calls/active); use status to narrow to live calls. It gains filters — status, direction, source, phoneNumber, flowId, contactId, campaignId, scheduleId, providerType, isLead, search, and sorting.
Integrate: Agent Skills for Claude Code, Codex, Cursor and any Agent-Skills-compatible tool — npx skills add Talkif-ai/skills — covering every job in these docs, verified against the public API. See Build with AI agents.
Docs: docs.talkif.ai restructured around tasks — Getting started, Concepts, Build agents, Telephony, Run calls, Integrate, Account and billing, Reference. Every previous URL redirects.
