TypedPython: #141 phase 2, GIL hand-off in snapshot-holding functions #154
Description
Phase 1 (feat/tp-eval-breaker) polls the eval breaker everywhere except in functions holding an array copy-in or an entry-globals snapshot. Phase 2 implements the hand-off there according to the decision issue (options (i)/(iii)). Done when: a second thread progresses during a long compiled array loop, with tests that a concurrent list resize gives the CPython-identical outcome (if (i)).

Merged into #159 (leader decision, 2026-10-04): with free-threaded 3.15t as the only build there is no GIL to hand off. The remaining work is re-validating arrays at poll points inside snapshot-holding functions (critical sections are suspended whenever the thread detaches), which #159 now covers. The rare changed-length/type case stays a decision in #152.
