Implements option a) of JUnit 5 recipe request: detect and replace implausible timeouts #452: JUnit Jupiter's @Timeout defaults to TimeUnit.SECONDS, so a value like @Timeout(10000) silently means ~2.8 hours and is almost certainly a millisecond mistake. The new ImplausibleTimeoutToMinutes recipe rewrites such second-based timeouts at or above a configurable threshold (default 1000s) to the equivalent minutes, e.g. @Timeout(10000) → @Timeout(value = 167, unit = TimeUnit.MINUTES), preserving the (likely erroneous) semantics while making the mistake obvious in review. It only fires when the effective unit is SECONDS (default or explicit) and the value is an int/long literal, leaving non-SECONDS units, non-literals, and plausibly small values untouched. The recipe is wired into JupiterBestPractices (and thus both JUnit 5 and 6 best practices), with recipes.csv regenerated accordingly.
