E40 Process Jobs + E94 Control Jobs + E30 communication state

GEM300 layer: SEMI E40-0705 Process Job and E94-0705 Control Job
state machines, plus the E30 §6.1 communication-state machine that
sits between HSMS SELECT and full GEM communication. Data-driven
via data/process_job_state.yaml and data/control_job_state.yaml,
mirroring the existing control_state.yaml pattern.

Wire coverage:
  S14F9/F10   CreateObject (CJ)              host -> equipment
  S14F11/F12  DeleteObject (CJ)              host -> equipment
  S16F5/F6    PRJobCommand                   host -> equipment
  S16F9       PRJobAlert                     equipment -> host
  S16F11/F12  PRJobCreate (simplified body)  host -> equipment
  S16F13/F14  PRJobDequeue                   host -> equipment
  S16F27/F28  CJobCommand                    host -> equipment

Process Job FSM exposes 8 states matching PRJOBSTATE bytes (E40 §10.3.2);
HOQ is reorder-aware (move-to-head against an insertion-order vector);
Stop/Abort on a Queued PJ routes through ABORTING so the host observes
PRJOBSTATE=7 on the wire (§6.3); alert_enabled is settable per-PJ for
PRALERT control; FSM dispatches through ProcessJobStore::on_change_
dynamically so a late set_state_change_handler() reaches existing PJs.

Hardening: loader rejects NoState (sentinel) as initial/from/to and
rejects `on: created` rows; static_asserts pin enum values to wire
bytes; ProcessJobStore is non-movable to keep the per-PJ this-capture
safe.

Server simulator cascades the full CJ -> PJ lifecycle on CJSTART so
the wire trace exercises every legal state. CEIDs 400/401 fire on CJ
state changes via the existing event-report pipeline.

Tests: 60+ new assertions across test_process_jobs, test_control_jobs,
test_communication_state, test_hsms_connection, plus loader and
messages round-trip coverage.
