Records trust in a signed mob plugin by writing
config :mob, :trusted_plugins, %{...} to mob.exs.
mix mob.plugin.trust <plugin_name>Resolves the plugin via Mix.Project.deps_paths/0, reads its
priv/mob_plugin.pub + manifest, displays the declared capabilities
(frameworks, permissions, gradle deps, plist keys) plus the
fingerprint, and prompts y/N before recording the entry.
Key rotation: if a different fingerprint is already trusted for this plugin name, this task warns and prompts for explicit confirmation before replacing the entry.
