cherry-picks: - Makefile.cbm: add 14 servicelink_*.c to PIPELINE_SRCS, add 14 TEST_SERVICELINK_*_SRCS test declarations, extend ALL_TEST_SRCS - pass_servicelinks.c: restore the LINKERS dispatch table to the full 14-entry list and remove the empty-table guard - pipeline.c: allocate cbm_sl_endpoint_list_t at function top (alongside path_aliases) so cleanup can free it safely even when the early cancel check goto's into cleanup before ctx is declared - test_main.c: register the 14 suite_servicelink_* test suites --- Makefile.cbm | 34 +++++++++++++++++++++++++++++---
