v0.2.1

Fixes and performance

• Fixed mix vibe startup stalls caused by stale server metadata, occupied default server nodes, and web endpoint port conflicts.
• Fixed TUI prompt repaint alignment so typed text, the prompt editor, and the cursor stay in sync.
• Improved TUI typing responsiveness by reusing cached body rendering for editor-only input.
• Removed expensive skill scans from normal slash-command autocomplete and cached command/skill autocomplete items.
• Reduced prompt submit latency by deferring context preparation out of the Enter keypress path.
• Simplified the Reach CI gate to use strict architecture and smell checks without a separate cycle wrapper script.

Architecture and rendering

• Tightened Reach architecture policy around storage, event, transport, plugin, CLI, terminal, Markdown, presentation, and UI-state layers.
• Moved reusable terminal rendering primitives from Vibe.TUI.* to Vibe.Terminal.* and guarded the old namespaces from returning.
• Guarded generic CLI code from depending on TUI internals while preserving explicit TUI entrypoints and storybook tooling.
• Added direct tests for extracted helper boundaries and hardened selector replay, picker presentation, CLI rendering, and Markdown fencing.
