* fix: pass agentId in CLI message command to enable session transcript writes
The CLI `openclaw message send` command was not passing `agentId` to
`runMessageAction()`, causing the outbound session route resolution to
be skipped (it's gated on `agentId && !dryRun`). Without a route, the
`mirror` object is never constructed, and `appendAssistantMessageToSessionTranscript()`
is never called.
This fix resolves the agent ID from the config (defaulting to "main")
and passes it through, enabling transcript mirroring for all channels
when using the CLI.
Closes#54186
* fix: format message.ts with oxfmt
* fix: use resolveDefaultAgentId instead of cfg.agent
* fix: restore CLI message transcript mirroring (#54187) (thanks @KevInTheCloud5617)
