chore: release 0.2.1

Language coverage release. 10 new DAP adapters bring built-in support from
12 to 22 languages, prioritized by language popularity and DAP adapter
maturity.

ADDED
- Dart (with optional Flutter) — auto-detects `flutter` on PATH and adds
  a "Launch Flutter app" configuration alongside the plain Dart file
  launch. Uses `dart debug_adapter` / `flutter debug_adapter`.
- Bash / Sh — `bash-debug-adapter` with automatic `bashdb_dir` probing
  from the mason package path.
- R — `vscDebugger` R-package integration. Preflights the package via
  `Rscript` and silently skips registration if it's missing.
- Elixir — `elixir-ls-debugger` with `mix_task` launch (default task
  `test`). Falls back to the mason package `debugger.sh` if the wrapper
  binary isn't on PATH.
- Haskell — `haskell-debug-adapter`.
- OCaml — `ocamlearlybird`.
- Zig / Nim / Crystal — routed through the existing `codelldb` adapter
  via filetype extension (no new adapter; just added filetypes to the
  existing codelldb configuration).
- F# — routed through the existing `netcoredbg` adapter (same
  `.dll`-launch flow as C#).

INTERNAL
- Extended `tests/test_adapters.lua` to cover the three new modular
  adapter modules (`dart`, `bash`, `r`).
- All new registrations follow the existing `find_executable` +
  `loader.register` pattern and silently skip when the required binary
  isn't found — matches the "no noise when prereqs missing" invariant of
  the previously-shipped adapters.
