feat(scheduler-core): add picker configuration fields (task 1.3)

Browse source 
Adds xce_scheduler_t.job_pick_plugin (global picker name), and on
xce_sched_queue_t: project_name + job_pick_plugin (per-queue override,
NULL = inherit global). Adds xce_sched_project_t.priority (scaffolding
only, no quota logic). sched_set_default_job_pick_plugin() is added but
not yet wired into sched_init() -- task 2.4 owns that, alongside
replacing the hardcoded "xce_sched_fcfs" literal.

Requirements: 2.1, 2.2, 2.3, 2.4
