feat: Add charmbracelet TUI for gt feed (gt-u7dxq)
- Add bubbletea and bubbles dependencies - Create internal/tui/feed package with: - model.go: Main bubbletea model with agent tree and event stream - view.go: Rendering logic with lipgloss styling - keys.go: Vim-style key bindings (j/k, tab, /, q) - styles.go: Color palette and component styles - events.go: Event source from bd activity - Update gt feed to use TUI by default (--plain for text mode) - TUI features: agent tree by role, event stream, keyboard nav Closes gt-be0as, gt-lexye, gt-1uhmj 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
