remove_workdir() now checks snprintf's result and skips a truncated path
instead of unlinking whatever it happens to name.

xce_scheduler --sim started with no shared resource pool when the shared
values came only from the recording's SnapshotEntry (license value=(none)),
so jobs needing a shared resource pended instead of dispatching. Two
defects caused it:
- Load side (snapshot_load.c): a resval was treated as shared only when
rv->host == NULL. The capnp round trip (write_snapshot_entry ->
decode_SnapshotEntry) reads a NULL host back as "", so every shared
resval in a .replay file was skipped. A NULL or empty host now means
the shared pool; only a named host marks per-worker data.
- Save side (snapshot.c, snapshot_wire.c): core->sharedInst and each
worker's resvals were walked with i < .count. zarray_t.count is the
number of filled slots, not the highest idx + 1, and both arrays are
sparse by resource idx, so higher-index values were dropped from the
snapshot. Both loops are now bounded by .caps, as repl_info.c already is.
New test test_snapshot_sparse_resvals.c covers the in-memory save/load,
the empty-host load, and the real sched_record_start() -> .replay ->
sched_sim_driver_start() round trip.
Regenerated fixtures/repl_trace_baseline/set_output.replay: its mid-run
snapshot now carries license, limit=cluster_slots and each worker's
limit=host_slots, which the old writer dropped (all other fixtures
unchanged).

Task 1.1: scripted REPL session over a contention replay (license, cluster
and host limits, parallel and alternative jobs); transcript, recordings and
--sim-verify result committed as fixtures and compared byte for byte.
