Brad Smith 62e937bf2b feat(plugins): expose register_slack_action_handler API
Plugins that post Block Kit messages with interactive elements (buttons,
overflow menus, datepickers, etc.) had no documented way to receive the
resulting click events. The plugin API exposed register_tool, register_hook,
register_command, register_platform, and register_context_engine, but
nothing for slack_bolt action handlers. The only workaround was to
monkey-patch SlackAdapter.connect from inside register(), which is
fragile and breaks on every Hermes update.

This change adds:

* PluginContext.register_slack_action_handler(action_id, callback) —
  validates inputs and queues the handler on the PluginManager.
  action_id accepts whatever slack_bolt.App.action() accepts (literal
  string, compiled re.Pattern, or constraint dict).
* PluginManager.get_slack_action_handlers() — accessor used by the
  Slack adapter at connect time.
* SlackAdapter.connect — after wiring its built-in approval and
  slash-confirm buttons, iterates the plugin-registered handlers
  and registers each via self._app.action(matcher)(callback). Each
  callback is wrapped defensively so a misbehaving plugin cannot
  crash slack_bolt's dispatch loop, with a best-effort ack on
  exception so Slack stops retrying the click.
* Defensive fallback when the plugin layer is unhealthy: a
  RuntimeError from get_plugin_manager() is logged and swallowed
  rather than blocking the gateway from starting.
* Test coverage in tests/gateway/test_slack_plugin_action_handlers.py
  for input validation, multi-plugin registration, the connect-time
  wiring, defensive exception handling, and the plugin-loader-
  failure fallback path.
* Documentation in website/docs/guides/build-a-hermes-plugin.md
  describing the new API alongside the existing register_command /
  dispatch_tool documentation.
