Fileoverview

AbortSignal linking helpers shared across EP HTTP clients.

Both BaseEPClient and DoceoClient need to compose an externally-provided cancellation AbortSignal (typically the inner signal exposed by withTimeoutAndAbort in OSINT tools) with an internally managed controller (the per-request timeout controller). Extracting the helper here ensures both call sites use identical event-listener and cleanup semantics — preventing leaks and double-abort regressions.

ISMS Policies:

• SC-002 (Secure Coding Standards) — bounded, cancellable network I/O
• PE-001 (Performance Standards) — pre-emptive cancellation frees rate- limiter tokens and connection slots when an upstream deadline expires
