Prevents Captain from being scheduled for replies or
inactive-conversation resolution when an inbox already has an active
AgentBot or Dialogflow integration.
## Closes
[CW-7834](https://linear.app/chatwoot/issue/CW-7834/prevent-captain-from-processing-agentbot-and-dialogflow-conversations)
## Why
Captain and an external inbox bot could both process conversations from
the same inbox.
## What this change does
- Distinguishes external inbox bots from Captain in the existing bot
predicate.
- Skips Captain reply scheduling when an external bot is active.
- Skips Captain inactive-resolution scheduling when an external bot is
active.
## Validation
- Connect an AgentBot to a Captain-enabled inbox and confirm Captain
does not reply or schedule inactive resolution.
- Enable Dialogflow on a Captain-enabled inbox and confirm Captain does
not reply.
- Remove the external bot integration and confirm Captain resumes normal
processing.
