Claude provider and compact session launcher

What's Changed

• Added a dedicated Claude Code provider backed by the embedded Anthropic Claude Agent SDK bridge, with streaming, multi-turn continuation, resume, steering, interrupt, permissions, approvals, questions, models, usage, and image input.
• Generalized ACP image prompts for capable clients while preserving path fallback for providers that do not advertise image support.
• Replaced the session launcher provider card grid with one compact provider selector that remembers the last choice and returns the reclaimed space to folder browsing.
• Expanded fake and live provider coverage across Codex, Claude Code, Gemini CLI, GitHub Copilot CLI, Grok Build, OpenCode, and custom ACP clients.
