Module messaging_adapter 

Messaging adapter plugin discovery and external plugin wrapper.

Plugin discovery

Plugins are searched in order:

1. ~/.config/ta/plugins/messaging/ — user-global
2. .ta/plugins/messaging/ — project-local
3. $PATH — bare executable with prefix ta-messaging-

The first matching plugin for the given provider name is used.

ExternalMessagingAdapter

Wraps an external plugin process and translates trait calls into JSON-over-stdio request/response exchanges. Each method call spawns a fresh process (plugins are stateless per-call).

Credentials

Credentials (OAuth2 tokens, IMAP passwords) are stored in the OS keychain under the key ta-messaging:<provider>:<address>. Plugins retrieve them via the keyring crate or by calling ta adapter credentials get <key>.
