feat: phase2 review fixes

- TIME injection: change from spaces to '2500' (hour>23) for NUMVAL trigger
- Runner: add .resolve() to work_dir to fix chdir+relative path breakage
- Coverage: per-target field overrides for DP#9-#12 (START-DATE=20240115 etc.)
- .gitignore: add compilation artifacts, temp scripts, test outputs
