Initial commit: Claude Code session viewer (Flutter macOS)

A desktop app that parses Claude Code .jsonl session logs and provides
a rich UI for exploring conversations, tool usage, subagents, and token
consumption. Features include project browser with auto-discovery of
~/.claude/projects, conversation timeline with inline subagent expansion,
agents overview, toolbelt chart, and token usage dashboard.
