v2.0.0 - modernized toolchain, hterm dropped, reconnect bug fixed

Major release. Most of the codebase has been refreshed from its 2021
state.

Breaking changes:
  - --term=hterm and the `term:` config key are no longer accepted.
    hterm support and its libapps dependency are removed; xterm.js is
    the only supported terminal frontend.
  - The `preferences { ... }` config block (hterm-only) is gone.
  - The config file at ~/.gotty is now YAML, not HCL1. Mechanical
    conversion: `key = "value"` -> `key: "value"`, `// ...` -> `# ...`.

Bug fix:
  - Keystrokes were sent N+1 times to the server after N reconnects,
    because xterm.js IDisposables returned by term.onData/onResize
    were discarded and deactivate() never detached the listeners.
