chore: release 0.1.0 — rename to turbo-debug.nvim

Rename from tiny-debugger to turbo-debug — inspired by Turbo Pascal,
the first IDE with a real visual debugger. This thing isn't tiny,
it's turbo charged.

CHANGELOG for 0.1.0:

Features:
- Zero-config debugging — one line install, everything works
- Modal keybindings (c/s/d/r/q/x/X/D/W/K/E/R/?), active only
  during debug mode, cleanly removed on exit
- Persistent breakpoints via persistent-breakpoints.nvim
- Inline virtual text — variable values in source code
- Hover (K), watch (W), REPL eval (E) from the code window
- Help splash (3s auto-dismiss) + manual help (?)
- Debug mode chrome — winbar indicator, cursor highlight
- dapui integration — controls toolbar, labeled panels
- which-key support — <leader>d debug group auto-registered
- quit_exits_mode option

Adapters (12 languages):
- Python (debugpy + venv detection)
- Rust (codelldb + cargo build + vim.ui.select picker)
- Go (delve), C/C++/Swift (codelldb)
- JavaScript/TypeScript (js-debug-adapter)
- C# (netcoredbg), Java, Kotlin, PHP, Ruby, Lua (osv)

Keybindings:
- <leader>dd — toggle debug mode
- <leader>dx / <leader>dX / <leader>dD — breakpoints (always)
- c s d r C x X D W K E q R ? — modal (debug mode only)
