Add submarine TUI prototype with mock data

Bubble Tea prototype for browsing repositories with many nested git submodules: collapsible tree, pins shown as ref + distance, summarized issue words with severity levels, detail pane, async loading via a Provider interface backed by mock data. Includes docs/ with requirements, state model, UX guide, architecture and decision log, plus AGENTS.md. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
