v0.2.1: Custom three-panel UI, 5 bugfixes

Highlights

• Telescope removed — replaced with a custom three-panel float UI (zero external dependencies)
• 5 UI bugfixes — fuzzy highlights, cursorline, padding, autocomplete, multiline prompts
• 80 tests, all passing

What's New

Custom Float UI

Container frame ("BotGlue" title, model badge footer) with three borderless inner panels:

• Filter — fuzzy search with matchfuzzypos match highlighting
• History list — frequency-sorted, inline model tags, full-width cursorline
• Prompt editor — multi-line, with placeholder text

Active panel indicated by yellow divider highlight. UI auto-closes on focus loss.

Bugfixes

• Fuzzy match highlighting — correct for multi-byte UTF-8 (Cyrillic, CJK) via byteidx() conversion
• Cursorline coverage — model tags now inline, so cursorline extends across full row
• Symmetric padding — 1-space padding on both sides of history list entries
• Autocomplete suppression — sets both cmp_enabled (nvim-cmp) and completion (blink.cmp) buffer vars
• Multi-line prompts — newlines replaced with spaces in list display, preventing nvim_buf_set_lines error

Claude Interaction

• System prompt now includes selected text for better AI context
• _extract_result returns (result, error) tuple with graceful fallback

Requirements

• Neovim 0.10+
• Claude Code CLI in PATH
