feat: add sidekick.nvim and haunt.nvim with AI and bookmark integration

- Add sidekick.nvim: Next Edit Suggestions (NES) via Copilot LSP, integrated
  AI CLI terminal, and Snacks picker send action (<Alt-a>)
- Add haunt.nvim: in-buffer annotation/bookmark manager with Snacks picker
  and 6 keymaps (<leader>ha/ht/hd/hn/hp/hl)
- Wire blink.cmp <Tab> to chain snippet_forward -> NES -> inline completion
- Expose haunt_all and haunt_buffer as Sidekick prompt contexts
- Suppress lua_ls "Loading workspace" progress bar via Noice route
- Update README to document all new plugins, keymaps, and post-install steps

 - **Phased Loading**: Async, non-blocking startup using a phased `VimEnter` queue for a snappy experience.
 - **Unified Registry**: Configuration is managed via a global `_G.Config` registry, ensuring cross-plugin consistency.
 - **High Performance**: Featuring **blink.cmp** (Rust-based completion) and optimized **Snacks.nvim** components.

+- **AI-Powered**: Native integration with **GitHub Copilot** — inline completions via **blink-copilot** and multi-line refactoring via **Sidekick.nvim** Next Edit Suggestions (NES).
 - **User-Centric QoL**: Hybrid line numbers, autosave-on-edit, and seamless system clipboard integration.
 - **Resilient & Portable**: Intelligent terminal title management (Kitty + Fallback), automatic project root detection, and machine-local override support.
 - **Lean & Readable**: ~850 lines of Lua code (excluding comments and blanks).
