Routes all 26 blocking xcecli_* call sites across ~24 commands through
xcetest_run_interruptible(), wires xcetest_set_active_connection() at
execute_line()'s dispatch point (active_ctx->ctx, read fresh per
command), and fixes main()'s REPL loop to distinguish a real EOF from
an EINTR-interrupted readline() so Ctrl-C at an empty prompt discards
the line instead of exiting the session.
Live-discovered and fixed bug-1794: fill_job_alloc() never initializes
xce_job_alloc_t's nres_shared/allocs_shared fields -- harmless as stack
garbage before this task, genuine heap garbage once moved into a
heap-allocated ctx block (a necessary consequence of the adapter's
heap-only precondition). Fixed by switching all ~26 call-context
allocations from malloc to calloc uniformly. Also fixed an argv-aliasing
hazard: cmd_hello/cmd_jobckpt's -m values aliased optarg, which
execute_line() frees immediately after return including on the
abandoned path -- now strdup'd into the heap block.
Also closed a safety-critical gap this task's own design introduced
(bug-1795): before this task the REPL was fully synchronous, so
leave_ctx() (called by up/quit) could never run while an RPC was
outstanding. An abandoned worker can now persist past command
completion, so leave_ctx() tearing down the connection could
use-after-free it. Fixed via xcetest_wait_connection_idle(), which
blocks on the same per-connection semaphore the adapter already
tracks, then releases it, proving no worker is active before teardown.
Proven with a deterministic white-box RED->GREEN test, since the race
itself is too timing-dependent for a black-box test to reliably force.
