feat: bug fixes, lazy.nvim-style controls, auto-update checking, repo polish

Phase 1 - Bug fixes:
- Fix extmark rendering in text.lua (table vs string hl handling)
- Fix timer leak: WinClosed autocmd now triggers view.close()
- Add GOBIN/GOPATH/~/go/bin awareness to is_installed() and new bin_path()
- Reject update_all() while tasks running (race condition fix)
- Implement _toggle_details with full binary info expansion

Phase 2 - Lazy.nvim-style controls:
- U = Update all, u = update cursor binary
- I = Install all missing, i = install cursor binary
- x = Abort, CR = toggle details, q/Esc = close
- Line-to-binary mapping for cursor-aware actions

Phase 3 - Auto-update checking:
- New checker module with go list/go version -m integration
- auto_check config option (daily/weekly/custom frequency)
- Persistent state in stdpath('data')/glaze/state.json
- :GlazeCheck command for manual checks
- Update indicators in UI (version info + arrows)

Phase 4 - Repo polish:
- MIT LICENSE file
- Doughnut-themed README with badges and Why Glaze? section
- Updated help docs with all new features/keybinds/API

+## 🤔 Why Glaze?
+
+Every Go-based Neovim plugin reinvents the wheel: each one ships its own
+`go install` wrapper, its own update command, its own version checking.
+
+**Glaze stops the madness.** Register your binaries once, manage them all from
+one beautiful UI. Plugin authors get a two-line integration. Users get a single
+`:Glaze` command.
 
 ## ✨ Features
 
 - **Centralized binary management** — Register binaries from any plugin, update them all at once
-- **Lazy.nvim-style UI** — Floating window with progress bars, spinners, and status indicators  
+- **Lazy.nvim-style UI** — Floating window with progress bars, spinners, and status indicators
+- **Cursor-aware keybinds** — `u` updates the binary under your cursor, `U` updates all
 - **Parallel installations** — Configurable concurrency for fast updates
+- **Auto-update checking** — Daily/weekly checks with non-intrusive notifications
+- **GOBIN/GOPATH awareness** — Finds binaries even if not in PATH
+- **Detail expansion** — Press `<CR>` to see URL, install path, version info
 - **Charmbracelet aesthetic** — Pink/magenta color scheme that matches the Charm toolchain
 - **Zero config for dependents** — Just register and go
 - **Callback support** — Get notified when your binary is updated
