Partial object rules with dynamic keys (e.g. `violations[k] if { ... }`)
only produced a single entry instead of collecting all bindings. Two
independent bugs caused this:
1. Interpreter: the early-return optimization in eval_output_expr_in_loop
checked whether the rule_ref was constant but never verified whether
the key expression was also constant. A variable key like `k` was
treated as constant output, causing the loop to exit after the first
iteration. Fixed by gating early-return on key_expr constness.
2. RVM: compute_rule_type incorrectly classified `p[k] if { ... }` as
PartialSet instead of PartialObject. OPA v1 semantics define this
form as a partial object (key -> true). Fixed the classification and
added compiler error guards for patterns the RVM codegen cannot yet
handle (constant keys, nested bracket keys), ensuring graceful
fallback to the interpreter.
The OPA test harness now skips RVM validation per-case when partial
object compiler errors are raised, rather than blanket-skipping entire
folders. This preserves RVM coverage for unrelated tests in the same
folders.
Closes #712
