Add job_runs lifecycle.triggers.on_value_change

[radakam]

Changes

Add lifecycle.triggers.on_value_change for resources.job_runs (direct engine). The run is recreated when the resolved expression changes. ${resources.*} refs become deploy-graph dependencies. Multiple triggers are separate list entries (one key each). Removing the trigger updates state only and does not start a new run.

Why

job_runs already support on_bundle_deploy and on_file_change. Watching a resolved value (variable or resource id) is the remaining trigger from the job_runs design, so a run can re-fire when an upstream resource or interpolated value changes.

Tests

• Unit: validate_job_run_triggers (empty/whitespace/two-keys/prevent_destroy), PrepareState/PrepareInputConfig, DropJobRunValueChangeConfigRefs, OverrideChangeDesc (remove vs change).
• Acceptance on_value_change: two expressions; changing one var recreates (other fingerprint stays); removing both triggers is an update with no run-now.
• Acceptance on_value_change_ref: concatenated ${resources.jobs.other.id}-${resources.jobs.extra.id}; depends_on includes both jobs; persisted state is [OTHER_ID]-[EXTRA_ID]; READPLAN="" and READPLAN=1.
