Description

Unit test for relative JUMP targets, see
docs/GRAMMAR/ADR-records/ADR_20261007_GRAMMAR_FIXES.md

One unit of intensity is emitted from a 1x1 m square.
- Back jumps to PREVIOUS(2), i.e. to Target, 'iter' times in total
(JUMP ... ITERATE), so the Mon monitor in between is passed 'iter' times
and reads Mon_I = iter.
- Skip jumps to NEXT(2), i.e. over Skipped and onto Landed, so
Skipped_I = 0 and Landed_I = 1.

Before the fix, relative targets were used as absolute component indices:
JUMP PREVIOUS(n) crashed the code generator and JUMP NEXT(n) went to
component n. JUMP PREVIOUS is PREVIOUS(1) and JUMP NEXT is NEXT(1).

Examples

• Test: iter=3 Detector: Mon_I=3
• Test: iter=3 Detector: Landed_I=1
• Test: iter=3 Detector: Skipped_I=0
