- Add --vcpus N argp option in main.c; store in myconf.vcpus
- Replace inline argp guard with validate_vcpus() call (returns -EINVAL for <=0)
- Add validate_startup_config() in startup_validation.c: returns 0; writes
deprecation warning into caller-supplied warn_buf when vcpus key present
- Wire validate_startup_config() into myapp_run() after conffile resolved;
emit WARN() if warn_buf non-empty (Req 4.4)
- Remove vcpus field from cluster_config_t (clusterconfig.h)
- Preserve capnp ordinal: vcpus @7 -> vcpusDeprecated @7: Void in controller.capnp
- vtaskmgr_init uses only myconf->vcpus with hardcoded default 8
- Add stub C types in typemap.h for capnp schema extensions from task 1.1
- 96 tests pass
- myapp.c: capture am_i_primary() into is_primary (avoids redundant
second probe call); after load_primary_config() succeeds, record
CTRL_PRIMARY role via atomic_store_explicit so cluster_init_phase2()
sees the correct role (ha_init() defaults to CTRL_STANDBY)
- myapp.c: add #include "ha.h" for CTRL_PRIMARY, atomic_store_explicit,
and memory_order_release
- cluster.c: cluster_init() wrapper now calls cluster_fini(c) before
returning on create_ssl_context failure, hook failure, and
cluster_init_phase2 failure — prevents SSL ctx and phase1 resource leak
