feat(scheduler-allocator-runner): declare the allocator plugin contract (task 1.2)

Browse source 
xce_sched_allocator_iface_t (optional accepts guard + plan_init/next/fini)
and the sched_allocator_run() entry point in sched/alloc_iter.h; the
plugin's const allocator_iface reference, forward-declared in plugin.h
with the picker_iface ownership rule. No plugin uses them yet.

- Done when the full scheduler suite builds and passes under ASAN with no plan generator taking a scheduler object, and the poisoned-core test shows identical plan sequences for parjob

- Add the allocator contract (optional acceptance guard plus plan initialise / next / finish) next to the plan-iterator contract, and declare the framework allocation entry point there
- Add the plugin's reference to its allocator contract, documented with the same ownership rule as the job-picker contract: static storage in the plugin file, never freed by the registry, NULL for non-allocator plugins
- Done when the scheduler and its suite build and pass unchanged with the new declarations present and no plugin using them yet

## Implementation Notes
- Build/test only in the dedicated dir `src/build.alloc` (`bash src/tools/xce-build.sh scheduler asan build.alloc --jobs N --incremental`; baseline 90/90). Another session uses `src/xce.build`.
- Several white-box scheduler test targets run with `detect_leaks=0` because their fixtures are not torn down (`testsuite/meson.build:1756`); a leak summary from running such a binary directly is pre-existing, not a regression. New tests that assert "no leak" (3.3) need leak detection on for their own target.
