Implement the TuiMaterializer — the glue layer between the Output
Rendering Framework and the Textual widget tree. It maps ElementHandle
events from A2A task updates to Textual widgets.

Key design:
- TuiMaterializer implements the MaterializationStrategy protocol
- Widget registry maps element kinds to Textual widget factories:
  panel → RichLog, table → DataTable, progress/status → Static
- Per-session isolation: each tab gets its own materializer instance
  with independent widget map
- Streaming via on_element_updated pushes incremental deltas directly
  into mounted widgets
- Same widget tree serves TUI, Web (Textual Web), and IDE plugin
- Callbacks (on_widget_created, on_widget_removed) let the host screen
  mount/unmount widgets into the DOM
- Thread-safe via internal lock on widget/snapshot maps

New files:
- src/cleveragents/tui/materializer.py — TuiMaterializer class
- features/tui_materializer.feature — 20 BDD scenarios
- features/steps/tui_materializer_steps.py — Behave step definitions
- robot/tui_materializer.robot — 12 Robot Framework integration tests
- robot/helper_tui_materializer.py — Robot helper script

Quality checks: typecheck (0 errors), lint (clean), format (clean),
unit_tests (20/20 pass), integration_tests (12/12 pass)

Implement the TUI MainScreen using Textual >= 1.0 (ADR-044) with:
- CleverAgentsApp: root App subclass with Dracula theme
- MainScreen: primary chat interface with 3 sidebar states (hidden/visible/fullscreen)
  cycled via shift+tab
- Sidebar: right-docked collapsible panel for plans and projects
- Conversation: scrollable message stream with block cursor navigation
- SessionTabs: multi-session tab bar (auto-show with >=2 sessions)
- Throbber: rainbow gradient (12 color stops, 15fps) and rotating quotes loading
- PromptArea: input prompt with mode indicators and persona bar
- FooterBar: context-sensitive hotkey reference
- Dracula theme: canonical color palette with semantic token mapping
- Safety behaviors: double-tap ctrl+c quit (5s window), escape cascading
- Textual Web compatibility maintained (App subclass)

Add textual>=1.0.0 as project dependency in pyproject.toml.
Behave BDD tests for all widget states, theme constants, and behaviors.
Robot Framework integration tests with helper scripts.
