fix(tests): dedupe imports + permission-mode types from #202 consolidation

[arul28]

Fixes the typecheck failures on main after the test consolidation in #202.

• ctoWorkerLifecycle / linearIntake / linearSync had duplicate import lines (TS2300).
• prRebase.test.ts under-typed the lazy resolverUtils handles (TS2322) — corrected to AiPermissionMode -> AgentChatPermissionMode.

Local typecheck clean.

Greptile Summary

This PR fixes TypeScript compilation failures introduced by the test consolidation in #202. It removes duplicate import statements (TS2300) in three CTO service test files and corrects the lazy variable type annotations in prRebase.test.ts from generic string to the proper domain types (AiPermissionMode → AgentChatPermissionMode), matching the actual signatures of mapPermissionMode and mapPermissionModeForModelFamily in resolverUtils.ts.

Confidence Score: 5/5

Safe to merge — changes are purely type/import cleanup with no runtime impact.

All four files contain only import deduplication or type annotation corrections in test files. The types used (AiPermissionMode, AgentChatPermissionMode) are verified to be correctly exported from shared/types, and the function signatures in resolverUtils.ts match exactly. No logic changes, no security implications.

No files require special attention.
