Log Message:
javascript skill: document js.on_exit() scope + forced-termination semantics

js.on_exit() evaluates its handler string in the script's GLOBAL scope (it
compiles the string against the global object), so a handler function nested in
another function is unreachable and throws silently at exit. It also fires on
forced termination (operator-terminate / SIGTERM), which -- unlike a thrown
exception -- does NOT run catch/finally (verified empirically via SIGTERM +
file markers). New 'Script lifecycle: exit handlers' section covers the
global-scope requirement, the finally-vs-on_exit distinction, and the
out-of-process testing caveat.
