fix(ci): unbreak main — drop the orphaned AUTOMATION_COUNTED_ACTIONS export

[JSONbored]

Closes #10109

dead-exports:check — part of test:ci — is red on a clean main, so every open PR inherits the failure and none can go green. Same class of breakage as #9944.

What was wrong

AUTOMATION_COUNTED_ACTIONS existed for exactly one consumer: the action IN (...) restriction in queryAutomationRows. #10013 removed that filter on purpose — the read now selects every verdict in the window, because a human signal (reevaluation_actor, reevaluation_reason = 'maintainer_request') can ride a non-deciding verdict such as a label or an update_branch, and the old filter dropped those rows so a PR a human had actually touched read as automated.

The fold still classifies enacted / held, but it tests AUTOMATION_ENACTING_ACTIONS and AUTOMATION_HOLD_ACTION separately — it needs to know which half matched, so the union is of no use to it. The symbol has had no reference of any kind since #10013; #10089 touched the file without re-homing it.

The change

Delete the export. Its one piece of real documentation — these two sets together are what DECIDES a PR — moves onto AUTOMATION_HOLD_ACTION, together with the reason there is deliberately no exported union: a constant naming a set nothing selects on invites the reader to believe the read still restricts by it, which is the exact misreading #10013 existed to correct. Leaving that unsaid is how the symbol would get reintroduced.

Verification

• npm run dead-exports:check → no exported symbol is unreferenced outside its own file
• npm run typecheck clean
• test/unit/automation-rate.test.ts — 25 passed, file untouched. That is the evidence the symbol was load-bearing for nothing: no test needed adjusting, because no behaviour changed.

Zero runtime diff — the deleted line is a const no code path read.
