fix(supervisor): stop on unclassified bot transactions

[phroi]

Why

Committed bot transactions with action evidence that cannot map to a supervisor outcome should stop the live loop as an incident instead of continuing as a non-terminal unknown result.

Changes

• Classify committed bot transactions with unclassifiable action counts as terminal unknown.
• Preserve the committed tx hash and action evidence in the supervisor result.
• Add regression coverage for the terminal unknown classification.

Code Review

This pull request updates the bot transaction classification logic in the supervisor. When a bot transaction is committed but contains no classifiable actions (resulting in an "unknown" outcome), it is now treated as terminal with a specific reason. A corresponding unit test has been added to verify this behavior. There are no review comments, so I have no feedback to provide.
