/claim #9874

Problem

When a Cause contains both a typed failure (Fail) and a defect (Die) or interruption, foldZIO / catchAll uses Cause.failureOrCause and will recover from the typed error, silently dropping the defect/interruption.

Repro from the issue:

val t: Throwable       = new RuntimeException("boom")
val dieCause           = Cause.die(t)
val combinedCause      = dieCause && Cause.fail("boom")

ZIO.failCause(combinedCause).catchAll(_ => ZIO.debug("handled")) *> ZIO.debug("Success")

Fix

Change Cause.failureOrCause (and failureTraceOrCause) to return the non-recoverable part (stripFailures) whenever the Cause contains defects or interruption.

This ensures typed error recovery cannot mask defects/interruption.

Tests

Added regression test:

• ZIOSpec > catchAll > does not recover from typed errors when the cause contains defects (issue 9874)

Ran locally:

sbt -Dsbt.supershell=false "clean" \
