fix(issue-33): subscriber exit codes are named on both sides; wait keeps a spent budget at rc 2; G-8 is deterministic

- job_subscriber.py returns only named codes (RC_COMPLETED 0, RC_ERROR 1,
  RC_NO_EVENT 2, RC_BROKER_UNAVAILABLE 3, RC_WALL_CLOCK 4). The wrapper
  mirrors them as SUB_RC_* and compares subscriber codes only by name; a test
  keeps the mirror equal to the Python constants and forbids numeric
  comparisons of $sub_rc/$sub_exit and numeric `return` in the subscriber.
- `delegate-job wait` passed the subscriber's code straight through, so a
  spent budget would have reached its callers as 4; it is 2 again (B7 fails
  without the mapping).
- tier1 G-8 gave both clocks 0.5 s and raced; the wall clock now runs out
  first by construction (idle 30 s) and the test asserts RC_WALL_CLOCK.
  Other subscriber rc asserts use the names.
